I created a Terrain Collision code so that a player walks on top of the terrain and it works just fine. However, if I add another piece of terrain and try setting up the collision with that piece, the terrain collision will only work with the new piece and wont work with the original. Does anyone have any idea how to make the collision work with both pieces?

+ Code Snippet

	while ( LoopGDK ( ) )
	{
		//Gets the terrain height under the player
		float Terrain1 = dbGetTerrainGroundHeight (1,dbObjectPositionX(3),dbObjectPositionZ(3));
		float Terrain4 = dbGetTerrainGroundHeight (4,dbObjectPositionX(3),dbObjectPositionZ(3));
		PlayerSpawn();
		Hud();
		//Object 3 is the player, the codes put the player at terrain height
		dbPositionObject(3,dbObjectPositionX(3),Terrain1,dbObjectPositionZ(3));
		dbPositionObject(3,dbObjectPositionX(3),Terrain4,dbObjectPositionZ(3));
		// update the screen
		dbSync ( );
	}

It's not checking which piece of terrain it's over. It's positioning the player at the original ground height, then the new ground height simultaneously.

The quick, and in my opinion lazy method would be to ensure that at no point your terrain's height is 0. Then, you would simply add two new if statements replacing the code that adjusts the player's height.

+ Code Snippet

//Object 3 is the player, the codes put the player at terrain height
if(Terrain1!=0)		dbPositionObject(3,dbObjectPositionX(3),Terrain1,dbObjectPositionZ(3));
if(Terrain4!=0)
dbPositionObject(3,dbObjectPositionX(3),Terrain4,dbObjectPositionZ(3));

The correct way to achieve what you'd like to achieve is to check if the player's X and Z coordinate's are within those of the terrain's, but this would work as a quick fix, while you hammer a better way out.

My site, for various stuff that I make.
