If only makehuman made the creation of clothes easier and not require blender.

I've never really thought about that way. I developed that habit in my old qbasic days. I tend to make very nice looking spaghetti code so I like to make sure the scope is super obvious. That and I code at night on low sleep after work. I make all sorts of mistakes. I'm quite sure i have variables that are never used in this script. But I will take it in mind. Now i'm 8 hours overdue from sleep. Now I have 667 posts!

I've been doing some coding on a bunch of Left 4 Dead style stuff and this is the latest script I have. A simple use timer. I haven't tested it very hard, but there should not be any glaring bugs. Information about the script:

Title:			Use Timer
Author:			Einlander
Start Date:		5-22-17
Version:		2
Description:	A simple Left 4 Dead style use timer
Notes:
				WHAT IT DOES: Allows player to use a script to force player/user to use an item for a set period of time.
				Think Left 4 Dead when you need to pour gas or start generators.
				WHAT IT DOESENT DO: It does not immobilize the player/user. 
									It does not cancel when the player/user looks away or is too far.
Changelog:
	1	-Initial release
	2	-style changes small fix
		added self.entity:SetKeyValue("type","use_timer") .
		This will help when trying to figure out what you are using and adjust accordingly. 
		ie:detect you are using the use timer and make it so the player cant move
		-in Script:Start changed self.completed to true to prevent activating when not targeting entity.
	3	-complete rewrite with less code, and smarter time management

added self.entity:SetKeyValue("type","use_timer") . This will help when trying to figure out what you are using and adjust accordingly. ie:detect you are using the use timer and make it so the player cant move.

in Script:Start changed self.completed to true to prevent activating when not targeting entity.

On my system any more than four skinned characters causes massive slowdowns.

mySurface = Self.entity:GetSurface(0)

May 3, 2017

I might give it a try this time. I will be needing grenades and and even harder Molotov cocktails in my game. So I might as well make them now.

May 3, 2017

To go even further, you would need to WORLD PICK from the controllers feet to the ground. This will return a PICKINFO you would be able to get the exact surface. pickinfo.surface:GetMaterial() would get you the material itself. pickinfo.surface:GetMaterial():GetPath() should get the filename itself without going through extra steps.

This will not work on terrains.

Amazingly I get the same first number every time even if I use the time as the seed. :/

April 20, 2017

I give up using debug mode after I start populating levels. I just use release mode and lots of print statements.

April 20, 2017

I would still need to pass arguments to the script though. I want the editor to pass '+fullscreen' when I debug, but I don't want to have the game start as fullscreen the first time it's run. I want to have it start windowed, have the player set the screen resolution and then write it to file. Then the next run it will be fullscreen. But while I debug I want to be able to just say, ignore the games settings and be fullscreen.

April 19, 2017

I am requesting an input box or a separate tab that will allow devs to add command line arguments that will be passed to the game when launched from the editor.

This will allow us to use the System:GetProperty without having to hardcode the values into the game.

It should be viewable now

Operating system or device - Leadwerks Version:

Windows 7 Pro x64
Leadwerks 4.2 Beta BuildID:1737986

Issue description (what happened, and what was expected):

Issue
- Models with physics that drop onto the character controller will bounce higher
[*]What was expected
- The model to hit the top of the character controller then fall off.

Steps to reproduce

Load the fps AI and events map
Pick up any entity
Look directly up
Drop it

The pickbox commands are all undocumented. I have never used them. If I remember correctly there use to be an option in the model viewer to create the hitboxes but they were removed. Send a message to Josh, he may be able to tell you what commands to use in c++.

April 6, 2017

The issue was, I assumed that if you reset the perspective view it would be the same as the front view, which is not the case.

If a person stands at (0,0,0) looking at z+(0,0,1) they would be looking into the screen. I assumed that was front, but that is actually the Back view. Looking at z-(0,0,-1) is that actual back view which matches the perspective view. Which is the opposite of most 3d modeling programs even blender in it's backward ways. Also 3d Level editors are the opposite of what Leadwerks has.

So basically Perspective view is the back view and not the front view. For me it's just a break in convention.

April 6, 2017

I guess that perspective view is the back view. I guess i'm just use to 3d modeling tools where z+ goes out the screen :/

April 6, 2017

If you reset your perspective view, then create something in front view, it will show the reverse placement on the x axis in the perspective view. http://i.imgur.com/iIKJH2H.png

April 6, 2017

In the Leadwerks editor has the front and back Views are reversed.

When GetDebugEntityBoxesMode is enabled without water enabled. The AABB displayed do not stay in place. If water is enabled, and you look up far enough, the AABB displayed begin to drift again.

Its alright as long as you never adjust the textures in leadwerks, or scale them or apply multiple texture's to a brush. Then it all falls apart.

February 25, 2017

The problem with vmf/maps are the uv's are not relative. they are absolute to the texture. so you need the texture to derive the uv's. There is probably some math to convert them without, but i have never seen it done.

February 25, 2017

I found a convoluted way to get it into a editor with the uv's in place. But you will have to add the textures back yourself.

You need 3 things:

Crafty : http://nemesis.thewavelength.net/index.php?p=45

Delgine : http://www.delgine.com/index.php?filename=product_deled

and a Delgine plugin: Map Importer http://www.delgine.com/plugins/viewPluginCategory.php?catid=39&catdesc=Importers

First you make your map in Leadwerks and export it to vmf.
Open it in Crafty and export it as Map
Import it in Delgine and export it as obj.
Import the Obj in your 3d editor.
- Y is UP and Z is towards you
[*]Scale all uv's to .1

[*]Add your textures back in. It will look exactly how it does in Leadwerks.

This is a lot of work though.

February 25, 2017

Let me know how that works. I would love to be able to export buildings from leadwerks.

You can get the material of a specific layer of the terrain, then from what I am seeing, check the current layers alpha. I would assume the lower the alpha the more intense the texture. it can get complicated ...
