collisioncallback?

[cassius]

I hve been using EntityDistance to trigger off events mainly because I don't understand collisioncallback. So maybe someone can halp.

:ets suppose I have a character called mycharacter and a door called door01.

I want door01 to open when mycharacter collides with it.

 

I know the code for opening the door its just the callback code I need.

I have checked the wiki but I need actual code.

Anybody?

#include "engine.h"

int DoorCollision(TEntity e1, TEntity e2)
{
if(GetEntityType(e2)==1)	// only interested in balls
	AddBodyForce(e2,Vec3(0,1000,0));
return 0;
}

int main(int argc, char* argv[])
{
Initialize();
Graphics(800,600);
CreateFramework();
DebugPhysics(1);

TBody door=CreateBodyBox(1,2,0.3);
MoveEntity(door,Vec3(0,1,0));
SetBodyMass(door,1);
EntityType(door,2);

TBody ball=CreateBodySphere();
MoveEntity(ball,Vec3(0,2,-8));
SetBodyMass(ball,1);
EntityType(ball,1);

TTerrain terrain=CreateTerrain(128);
EntityType(terrain,3);

Collisions(1,2);	// ball with door
Collisions(1,3);	// ball with terrain
Collisions(2,3);	// door with terrain

TCamera cam=GetLayerCamera(GetFrameworkLayer(0));
MoveEntity(cam,Vec3(0,2,-10));

SetEntityCallback(door,(BP)DoorCollision,ENTITYCALLBACK_COLLISION);

AddBodyForce(ball,Vec3(0,0,500));

while( !AppTerminate() and !KeyHit() )
{
	UpdateFramework();
	RenderFramework();
	Flip();
}
return Terminate();
}
