When I first used Leadwerks, I was trying to make a ball game like Marble blast I never really finished it, but the third person camera is working plus a small demo level. It contains the source code which people can perhaps use.

 

Please note that this was just a very simple test B) . That means.

• not the best soundtrack
  
• bad textures on my own models
  
• you can jump as long as their is collision (which results in climbing up walls))
  
• no camera collision
  

 

#include "engine.h" 

int ballCollision = 0 ;

	void _stdcall EntityCollisionCallback( TEntity entity0, TEntity entity1, byte* 
	position, byte* normal, byte* force, flt speed ) 
	{ 
	ballCollision = 1;
	}



int main(int argc, char** argv) 
{ 
Initialize(); 

//Create a graphics context 
Graphics(800,600); 

//Create a world 
if (!CreateWorld()) { 
MessageBoxA(0,"Error","Failed to create world.",0); 
goto exitapp; 
} 

//Create a camera 
TEntity cam=CreateCamera(); 
CameraClearColor(cam,Vec4(0,0,1,1)); 
PositionEntity(cam,Vec3(0,8.2,-4)); 



//Create a light 
TLight light=CreatePointLight(); 
PositionEntity(light,Vec3(0,10,0)); 
RotateEntity(light,Vec3(0,45,0)); 



Collisions(1,1,1); 

//Create a render buffer 
TBuffer buffer=CreateBuffer(800,600,BUFFER_COLOR|BUFFER_DEPTH|BUFFER_NORMAL); 

//load a scene
TModel scene=LoadModel("abstract::scene.gmf"); 
if (!scene) { 
MessageBoxA(0,"Error","Failed to load mesh.",0); 
goto exitapp;   
} 
EntityType(scene,1);

//body
TBody ballbody=CreateBodySphere();
SetBodyMass(ballbody,1.5);

//mesh

ScaleMesh(ballmesh,Vec3(1,1,1));

TMFI bro, TMFI

TMFI bro, TMFI

TMFI? Whats that? don't recognize the slang.

 

When I replay this game I have to say that I'm eager to continue with it again. But I there are other things do at the moment. Would be a fun game to play though. Not to hard to make as well.

I'm guessing it means To Much F*&%ing Information
