[Mem Usage Grows Continuously]

glad i could help

 

 

I had the same problem but your solution with the Garbage Collector helped me out too. Thank you very much

[SetEntityCallback]

Good evening.

I try to make simple collision Events ( when u hit the Invisible Trigger, a Sound starts to play etc) with Delphi 7.

Well the problem I have, is that when I hit my Trigger I get an AccessViolation. I know that this was reported as a Bug and Josh fixed it but still,

it is not working for me.

 

EntityType(MyController,1,1);

EntityType(CollisionBox,4,1);

Collisions(1,4,2);

SetEntityCallback(CollisionBox,@EntityCollisionCallback,ENTITYCALLBACK_COLLISION);

 

in my MainLoop i call this for testing:

MessageBox(CollisionInfo);

 

Here are some functions I made in order to make things easier for me:

 

procedure MessageBox(Text:string);

var Texture: TTexture;

begin

SetBlend( BLEND_ALPHA );

Texture := LoadTexture('abstract::textbox.dds');

DrawImage (Texture,10,10,600,120);

SetColor ( Vec4(255,255,255,255) );

DrawText(30,30,pChar(Text));

end;

 

procedure EntityCollisionCallback(entity0:TEntity;entity1:TEntity;position:Pointer;normal:Pointer;force:Pointer;speed:real );stdcall;

var VecPosition: TVec3;

begin

CollisionInfo:= GetEntityKey(entity0,'Name');

end;

 

 

Btw: The @T means the AdressOf(T) in Delphi

 

I hope someone can help me out, cause this is about to drive me crazy.

[Terrain collision ?]

What is a collider?

 

You need to set the terrain collision type, just like any other entity.

 

But how can I set this ?

I dont know how to access the terrain that is my scene.

 

Here is the code I have made so far

--require("scripts/hooks")
require("scripts/constants/keycodes")

--Register abstract path
RegisterAbstractPath("")
--Set graphics mode

       return
end

ShutDown= false

--Create framewerk object and set it to a global object so other scripts can access it

if fw==nil then
       Notify("Failed to initialize engine.",1)
       return
end

[Terrain collision ?]

Hello, i started working with colliders today and I have a question about it.

How can I create a Terrain Collider ?

Because in my code the BoxCollider still goes through the terrain.

[Random Rotation ?]

Someone else had the same issue. If I recall correctly, you're not doing anything wrong, it's an LE "feature". May want to search the forums for the other post and see if there were any fixes in that thread.

 

 

Ok thanks for the help.

I found out that the problem is the Particle Vertex Shader ( the particles.vert File )

After rewriting the file to my needs i saved it to particles_rain.vert and i told my rain.mat file to use this new shader.

Now its working wonderfully B)

[Random Rotation ?]

Hey there.

I want to make a simple rain effect with Particles.

For that i made myself a very simple Material for the Rain Particles.

Now I attach this Material with the Particle Emitter Script.

First that I tested the effect it worked how it should.

But after reloading the Script it changed the start angle of my particles so my rain looks like stuff ^^

 

For making stuff more clear, I made 2 Screenshots of my Problem:

 

How it should work

 

After reloading the Script:

 

Those are my Emitter Settings

 

Hope someone can tell me what I am doing wrong.

[LUA Load Scene]

Also for more debugging info when using the ScriptEditor, run the program using the debug build (the ladybug next to the green run arrow). This will help give helpful hints where your problems might lie...

 

 

Ok thank you very much for your help B)

I finally made it to load my Scene.

The problem was that the Standart Trees ( vegetation_tree_spruce_2.gmf )

is a proteced file. I didnt know that ^^

 

Anyway thanks again for your help and have a nice day.

[LUA Load Scene]

where are you trying to run this from? Inside the editor?

 

There are basically three types of lua scripts for LE:

1) object scripts - look at the firepit.lua or environment_atmosphere.lua for examples of these scripts that set up properties for the models

2) game scripts - look at fpscontroller.lua or driver.lua as examples of scripts that can be ran inside the editor in conjunction with an editor's scene

3) standalone scripts (which is what I consider the above script) that should be saved in the LE SDK's root directory and ran from the ScriptEditor.exe that is in the root directory. See example01.lua and example02.lua. These scripts can also be ran by dragging and dropping the file ontop of the engine.exe file inside windows explorer.

 

So save the example above into your LE SDK root folder and then run it from the ScriptEditor.exe (not from inside the Editor) and it should work.

 

 

Actually i do use the Script Editor.exe that is included with the Engine.

The Leadworks Editor itself is not open.

 

sorry for double posting ^^

 

 

Edit:

When you say strange what do you mean? Are you saying it crashes? More than likely your camera is below the terrain for the arctic SBX file, so it will look strange. 

 

Strange means for me that it simply crashed without giving an Access Violation or some other sort of Error.

 

 

Edit2: How to i enable or disable this ? I cant remember that i protected my own Test.sbx Scene

[LUA Load Scene]

Ok, I made more tests and i found something out >.<

Actually I CAN load some Scenes with this code... But only some.

 

The tunnels.spx example does work. The train.spx also... So does the deserthighway.sbx example.

But the terrain_arctic.sbx does the same kind of strange stuff as my Test.sbx did ?

 

Now I am really confused... o.O

[LUA Load Scene]

You are trying to use invalid methods for your objects. The scene variable does not have a camera. The previous line was correct: camera=fw.main.camera. You are also doing the same thing with the Update and Render methods. You should be using fw:Update() and fw:Render(). Also remember that LUA is a case sensitive language, so "Scene" is not the same variable as "scene".

require("scripts/constants/keycodes")

--Register abstract path
RegisterAbstractPath("")

--Set graphics mode
if Graphics(1024,768,0,60,0)==0 then
       Notify("Failed to set graphics mode.",1)
       return
end

-- Custom shutDown Variable
ShutDown= false

--Create framewerk object and set it to a global object so other scripts can access it
fw=CreateFramework()
if fw==nil then
       Notify("Failed to initialize engine.",1)
       return
end
SetGlobalObject("framewerk",fw)

scene=LoadScene("abstract::AndyTest.sbx")
camera=fw.main.camera
camera:SetPositionf(0,2,-2)

function ControlCamera()
      if KeyDown (KEY_W)==1 then  MoveEntity (camera, Vec3(0,0,0.1)) end 
      if KeyDown (KEY_S)==1 then  MoveEntity (camera, Vec3(0,0,-0.1)) end
      if KeyDown(KEY_ESCAPE)==1 then ShutDown=true end
end


while AppTerminate()==0 and ShutDown == false do
       fw:Update()
       fw:Render()
       ControlCamera()
       Flip(0)
end

 

 

Well my first version was like yours. But since i didnt worked for me i started to try out some stuff.

I assume the code u posted worked for you ? Since i just copy pasted it into the edtior ( changed the Scene back to test.sbx ) and ran my script.

But still, it does the same as it did before...

 

I´m using Win7 x64 ( maybe thats the problem ? ) but so far i didnt have any sort of trouble with the OS and the Engine.

EDIT: The Engine loads the Scene ( because the Console tells me that the Scene Files are getting loaded )

But after loading the last Scene Asset it just terminates. Kind of Strange.

[LUA Load Scene]

Hello everyone

I am still very new to Leadwerk Engine ( just got it yesterday ) and i have some sort of trouble with LUA.

Well mainly I am a Pascal/Delphi Programmer ( but the Pascal Header doesnt work with my Delphi 7 ( trouble with the inline command ) so i do learn LUA kind of fast.

My Problem is now that i want to load a Scene with LUA.

 

Actually I try to do it with

scene=LoadScene("abstract::Test.sbx")

.

 

The LUA Editor doesnt give me an Error and i can start my Game. But then nothing happens. The Game just closes and that it.

No Error, nothing.

 

And YES there is a GameLoop in my Source

 

Well, i hope someone can help me with this.
