Hey,

I'm wondering if its possible to have the NavMesh generate on imported MDL's set as prop or scene in the editor and set as Poly Mesh physics?

A year ago I used to always have to create invisible texture blocks over the MDL surface for the NavMesh to work on it, is this still the case for 4.0 - I was reading up yesterday that the editor should be able to handle NavMesh on MDL's if the physics is set right.

I wasn't able to get it working. - I tried both "Nav Obstacle" checked and unchecked.

Any insights?

Thanks,

Erika

Hey everyone,

I've been reading up on multiple tutorials for FPS weapon pick-ups and guns, and I'd like to establish melee weapons instead - now I can get it to work with 3.2, but I can't get it to work for 4.0 using the same steps.

Here are some of the resources I've been using:

Rick's Weapon Pickup - https://www.youtube.com/watch?v=VWBGtJ7NQ4Y

HippoKittie melee code - http://www.leadwerks.com/werkspace/topic/11251-melee-code-for-you-guys/page__hl__melee

Genebris Collission based Melee combat topic - http://www.leadwerks.com/werkspace/topic/11519-collision-based-melee-combat/page__hl__melee

HippoKittie thread on melee weapon (specifically Gladious one) - http://www.leadwerks.com/werkspace/topic/10472-enemy-ai-and-melee-weapons/page__hl__melee

Now the last one is the one I managed to get working a year ago back in 3.2 - but now I can't even get any of them to work with 4.0.

WeaponPickup.lua and stuff (default) doesn't seem to be working at all even with the default pistol gun prefab.

I created a trigger box - attached script - following Ricks older weapon pickup guide - and I get 2 different errors, Exception Error which crashes the editor, and another one - then when it does load up, no weapon shows up in screen.

I've also tried attaching the weapon prefab directly to my player character - it doesn't load up with anything - and if I use the default pistol prefab, it fails to load.

I'm guessing that somewhere in the code (because they're older) - its not needed to be adapted to work with 4.0.

The below are all scripts written by others, that have worked in previous versions that I'm attempting to get working with the new build.

Below is the FPSMeleeWeapon.lua

I've already had a look at that Macklebee, doesn't seem to be the issue,

Edit - turns out the scripts were referencing to automationmanager.lua and that in turn was referencing app.lua which does not exist in 4.0. took that out and everything runs fine.

December 29, 2015

Hey all,

I've build Navmesh, and have several different models setup (including crawler) with different AI scripts, (including 1 from the FPS default).

In all scenarios, the AI triggers are sort of working (as the debug print/call screen says its looking for player, player in range, etc etc)

However, all models are running in the same spot without actually moving. Navmesh seems to be looking fine.

I've tried setting physics to Polymesh & Polyhydron - in 1 case the model topples over and falls down...

I have everything enabled, collision type to Character - and mass i've tried everything from 5, 20, 50, 100, etc

Will get screen shots, and code samples in a sec...

December 29, 2015

Worked excellent, thank you, highly respect the video tutorials you've done on youtube, I hope to see many more!

I'm just getting back into it, its been over a year since 3.1 / 3.2 was out that I last made anything.

December 29, 2015

Hey,

I've been trying to adapt as much scripts as possible to work with the 4.0 version, and I've come across some issues with the Health Bar script,

The color function doesn't work. The bars stay black.

Script.offset = Vec2(0,0) --Vec2 "Offset"
Script.size = Vec2(160, 25) --Vec2 "Size"
Script.backgroundColor = Vec4() --color "Background color"

Script.overlayPath = "" -- path "Overlay" "Tex file (*tex):tex"
Script.overlay = nil
Script.player = nil
Script.backgroundColorFractioned = nil
Script.healthbarColorFractioned = nil

function Script:Start()
self.player = self.entity:GetParent()
if self.overlayPath ~= "" then
self.overlay = Texture:Load(self.overlayPath)
end


--background
local c = self.backgroundColor
self.backgroundColorFractioned = Vec4(c.x/255, c.y/255, c.z/255, c.w/255)

c = self.healthbarColor
self.healthbarColorFractioned = Vec4(c.x/255, c.y/255, c.z/255, c.w/255)
end


function Script:PostRender(context)
-- Background
context:SetColor(self.backgroundColorFractioned)
context:DrawRect(self.offset.x, context:GetHeight() - self.offset.y, self.size.x, self.size.y)

-- Healthbar
context:SetColor(self.healthbarColorFractioned)
local healthFactor = self.player.script.health / self.player.script.maxHealth
context:DrawRect(self.offset.x,context:GetHeight() - self.offset.y, self.size.x * healthFactor, self.size.y)


--Draw overlay
if self.overlay ~= nil then
context:SetBlendMode(Blend.Alpha)

context:DrawImage(self.overlay, 0, context:GetHeight() - self.overlay:GetHeight())

This doesn't work with LE 4.0 - constantly gives errors. Version 40 not supported when trying to test or debug..

Edit: just to clarify - works with default and brand new creation of project. But once you edit anything, or "save" specifically. Gives this error.

Create new project - loads up. Hit test, works. Add a box. Hit save, hit test, doesn't work. Seems like saving over the default map breaks it for LE 4.0

Edit 2: Possibly found a solution - delete all the files (not folders) in the project/yourprojectname folder such and doing a project - updates. It replaces the TEX original files with your owns current version. Works now.

Hey everyone,

I'm wondering if anyone knows of a updated tutorial or could assist with integrating the newest version of NeosisGUI with the newest version of Leadwerks.

I played around with NeosisGUI way back around 16 months ago and got it working back then with Leadwerks version from that time, however I've reset my project over and the steps to implement (from the old tutorial) aren't valid anymore with all the updates.

Any assistance would be greatly appreciated.

I'm not 100% how to reproduce the error.

After playing around with some of the backup saves (thank goodness for autosaves!! <3 <3 )

I believe this to just be a corrupt save.

My start.map was from 8:02 pm last night.

my backup367.map.bak was from 7:59pm last night. I renamed backup376.map.bak to just backup367.map and loaded it (a 3 minute earlier save) and it doesn't give the error.

There's no difference between the start.map and the several backups from before that as no work additions were done and no changes were done. I think perhaps maybe it failed to fully save and caused a corrupt file.

September 8, 2014

Good day,

Program was working fine yesterday, logged on today and it gives this error when opening the start.map . after pressing OK, the program shuts off immediately.

Exception_Access_Violation

Error: Top-level entity cannot be a bone.

This error is occurring in Leadwerks 3.2 standard edition.

On windows 7, with a Nvidia graphics card 650M model.

When opening the CPP files and debugging, or running the map on Microsoft Visual Studio 2013, it gives no errors there.

The error is on Leadwerks Editor.

September 8, 2014

So I guess the issue was the object I was walking into had no physics. So how could it interact with the player?

Thanks Aggror, as soon as you asked me about it removing from the scene, that's where I looked into.

September 8, 2014

Ok, wow. oooooooppss!

I set the parent of the item that I wanted to run into with Box option, and trigger together.

Then I checked "show physics" and it finally turned on.

Now, when I walk into the object (mdl, or pfb, it picks it up and removed the item from the game and puts it on the player)

So thats solved.

Now I need to get it to fire/animate, hehe.

September 7, 2014

Ok,

I got a single csg to work with it. I drew a simple square box, set it to trigger, added the script and .pfb. It worked.

But its not working when I use an .mdl or .pfb that has "limbs" or attachments to the scene.

Basically, I want to walk into a sword, and have it pickup a sword. I dont want to run into a box, to pick up a sword.

September 7, 2014

No, no hand icon.

Only when I remove the script, and set it to prop with a weight does it show a hand icon. Then I can pick it up like a regular prop object.

Once I add the script, it doesn't allow that anymore - doesn't matter if its a prop or trigger in physics, not getting a hand.

The weapon is not removed from the scene.

September 7, 2014

I'm not actually getting an error;

When I walk onto the item, or csg that is set as trigger, and that has both the weaponpickup.lua script, and weapon.pfb atached, it does nothing. It doesn't add the weapon to the player (but does in indie version)

I tried it in debug mode, and wasn't receiving any error

September 7, 2014

I'm playing around and still learning lua;

Am I on the right track in thinking that something along the lines of the below script could be used to toggle open/close an inventory?

A player would press the key " i " in game and it would open/close the inventory.

--Toggle the inventory on and off

if window:KeyHit(Key.i) then

self.sound.inventory:Play()

if self.inventory:Hidden() then

self.inventory:Show()

else

self.inventory:Hide()

end

-- then, in the function script start area... a sound would play when toggleing the inventory on or off.

self.sound.inventory=Sound:Load("Sound/Player/inventory_toggle.wav")

-- then at the top for scripts;

Script.inventoryon = false --bool "Inventory on"

-- then I would need to define what the inventoryon is? ??? -- this is what im working on now, trying to attach it to my inventory.lua script where it has the dimensions/color, etc.

self.inventory =

if self.inventoryon==false then

self.inventory:Hide()

end

Let me know if I have the right sort of idea... I'm trying, hehe

September 7, 2014

Good day;

I've been following Rick's weapon pickup tutorial to the letter (or I think I have) as well as the adaptation of the code by Macklebee where he changed it from a gun to a melee weapon called Gladious.

I was able to get the pickup script to work when I was using just the Indie version. And I think that when I upgraded to Standard and compiled things in CPP that it perhaps broke something within the scripts. At the moment I'm not proficient enough with coding to fully understand what could be wrong. If someone could take a peak and perhaps point me in the right direction, would be greatly appreciated.

IMPORTANT EDIT:

I think I got the camera working now. I made a new project, and copied everything over except SOURCE folder. Then in vs2013 - i re-compiled, and ran a fast debug, and did a release.

Now the camera works as intended. Everything is working now except for the inventory script.

Working on replacing : self.screenWidth = App.context:GetWidth() - to something that works. Im learning!

#include "App.h"

using namespace Leadwerks;

App::App() : window(NULL), context(NULL), world(NULL), camera(NULL) {}

App::~App() { delete world; delete window; }

bool App::Start()

{

int stacksize = Interpreter::GetStackSize();

//Get the global error handler function

int errorfunctionindex = 0;

#ifdef DEBUG

Interpreter::GetGlobal("LuaErrorHandler");

errorfunctionindex = Interpreter::GetStackSize();

#endif

//Create new table and assign it to the global variable "App"

Interpreter::NewTable();

Interpreter::SetGlobal("App");

//Invoke the start script

if (!Interpreter::ExecuteFile("Scripts/App.lua"))

{

System::Print("Error: Failed to execute script \"Scripts/App.lua\".");

return false;

}

//Call the App:Start() function

Interpreter::GetGlobal("App");

if (Interpreter::IsTable())

{

Interpreter::PushString("Start");

Interpreter::GetTable();

if (Interpreter::IsFunction())

{

Interpreter::PushValue(-2);//Push the app table onto the stack as "self"

#ifdef DEBUG

errorfunctionindex = -(Interpreter::GetStackSize()-errorfunctionindex+1);

#endif

if (!Interpreter::Invoke(1,1,errorfunctionindex)) return false;

if (Interpreter::IsBool())

{

if (!Interpreter::ToBool()) return false;

}

else

{

return false;

}

//Restore the stack size

Interpreter::SetStackSize(stacksize);

return true;

}

bool App::Loop()

{

//Get the stack size

int stacksize = Interpreter::GetStackSize();

//Get the global error handler function

int errorfunctionindex = 0;

#ifdef DEBUG

Interpreter::GetGlobal("LuaErrorHandler");

errorfunctionindex = Interpreter::GetStackSize();

#endif

//Call the App:Start() function

Interpreter::GetGlobal("App");

if (Interpreter::IsTable())

{

Interpreter::PushString("Loop");

Interpreter::GetTable();

if (Interpreter::IsFunction())

{

Interpreter::PushValue(-2);//Push the app table onto the stack as "self"

#ifdef DEBUG

errorfunctionindex = -(Interpreter::GetStackSize()-errorfunctionindex+1);

#endif

if (!Interpreter::Invoke(1,1,errorfunctionindex))

{

System::Print("Error: Script function App:Loop() was not successfully invoked.");

Interpreter::SetStackSize(stacksize);

return false;

}

if (Interpreter::IsBool())

{

if (!Interpreter::ToBool())

{

Interpreter::SetStackSize(stacksize);

return false;

}

else

{

Interpreter::SetStackSize(stacksize);

return false;

}

else

{

System::Print("Error: App:Loop() function not found.");

Interpreter::SetStackSize(stacksize);

return false;

}

else

{

System::Print("Error: App table not found.");

Interpreter::SetStackSize(stacksize);

return false;

}

//Restore the stack size

Interpreter::SetStackSize(stacksize);

return true;

}

When I run the game with debug - in leadwerks editor, it works fine (except inventory script) - it starts as the FPSplayer controller.

when I just hit play, the camera starts at 0,-2,3 or something, and it has no-clip/fly.

September 7, 2014

Thanks Aggror,

I'll play around with that and see if I can get it to work.

Guppy,

I have completely // marked out all camera settings in App.cpp for C++ but that did not solve the issue. Its not using the regular Lua camera settings.

September 7, 2014

I can get it compiled,

Then when I go back to Leadwerks editor - most the start-up errors dissapear,

Its stuck on;

Script Error

attempt to index global 'App' (a nil value)

Line 10

-------------- this is referring to line 10 of the inventory.lua script from tutorial 16/17 by Jorn Theunissen

function Script:Start()

self.screenWidth = App.context:GetWidth()

It also gives warning: Lua Sandboxing is Disabled.

Now, if I remove the inventory.lua script from my player, the game runs.

However, it's ignoring my FPSplayer controller, its spawning me at 0.0.0 in the middle of the map, with fly mode/walk thru walls. I also cant interact with objects.

September 7, 2014

I switched it from 32bit to 64bit for debugging;

And it gives

2 errors, 1 warnings.;

Warning "C4267:'argument'conversion from 'size_t' to 'const int', possible loss of data - main.cpp line 33

Which says on line 33 "if (String::Right(settingsfile, 6) == ".debug") settingsfile = String::Left(settingsfile, settingsfile.length() - 6);"

Errors are; LNK1104: cannot open file 'lua51.lib'

And; IntelliSense enumeration value is out of 'int' range.

EDIT: for the LNK1104 error, in project properties, linker, input, the discrepancies field has a error - this could be the reason for it.

EDIT2: my file paths show x86, when changing it to 64bit, it wants 64bit file paths. But I have x86 file paths. so I guess I need to use 32bit debug.

September 7, 2014

Ahh ok, the guide I had open before mentioned 2010.

I installed the VS2013, and it doesn't launch anything. It gives around 85-120 errors, then just closes.

Most errors are PDB errors, which I believe I can ignore, but theres also runtime errors (memory errors), .tex and .mat errors, which is weird as they dont give error in leadwerks editor.

Heres some of the last of the debug;

The thread 0x2204 has exited with code 1 (0x1).

The thread 0x1fbc has exited with code 1 (0x1).

The thread 0x2648 has exited with code 1 (0x1).

The thread 0xc40 has exited with code 1 (0x1).

The thread 0x2130 has exited with code 1 (0x1).

The thread 0x1d18 has exited with code 1 (0x1).

The thread 0xf68 has exited with code 1 (0x1).

The thread 0xf24 has exited with code 1 (0x1).

The program '[6912] MyGame2.debug.exe' has exited with code 1 (0x1).

Attempt to index global "app" (A Nil Value) (EDIT2: this error is caused by app.cpp something about null, or function.) nil & function are used in LUA, but not in C++, I didn't see any nil or function mentioned in app.cpp but there is 3 (NULL) as some things from the default are not defined.

I've tried build/rebuild, and running with and without debug.

EDIT; I solved error c4018 by replacing int i with size_t i on line 58 of main.cpp

September 7, 2014

I cant compile because it doesn't work with Microsoft Visual C++ Express 2010 (the free version) as the original LUA is created with a newer version. I would need to buy a version higher then 2010 to open it.

This is the error its giving me

September 7, 2014

I upgraded from Indie to Standard yesterday as I am interested in utilizing modules/apps and other benefits of programs like Neosis GUI which only works for C++.

I installed the DLC, and created a new project, using C++ instead of LUA.

My issue is moving my existing project over (my start.map) to the new project.

copy-paste of the map / texture / prefab / models , etc did not simply just work.

I had a look at Aggror's first tutorials 1-8 which covers Intro to C++, and models, and shapes, and other stuff using C++.

Do I need to start this first for the new project?

My existing project already works in Indie version by just hitting play. It loads the game fine.

Any help with this would be greatly appreciated. Let me know if I need to do a lot of set-up first, or if the existing project I worked on before should be able to just be copied over.

Edit; been reading other posts of users who upgraded. My understanding is that theres no default FPS character controller for C++ where as it has it in LUA. So I would need to do the follow along of Aggror's beginning tutorials to prepare the change over?

Edit2: I can get the map to copy, just can't run it. Gives a game.exe error. (I am assuming this is because the C++ isn't setup yet?)
