Terrain Generation Code.txt

MAKE SURE THAT YOUR CAMERA IS IN A POSITION THAT ALLOWS YOU TO SEE THE TERRAIN! MAKE SURE THE CAMERA'S Y
POSITION IS ABOVE 0, AND MAKE SURE THAT THE TERRAIN IS INFRONT OF THE CAMERA (EITHER MOVE THE
CAMERA BACK, ROTATE THE CAMERA AROUND, OR CHOOSE NEGATIVE GRIDX & GRIDZ VALUES WHEN CALLING THE TERRAIN
CONSTRUCTOR).

COPY AND PASTE INTO TERRAIN CLASS:

	private RawModel generateTerrain(Loader loader){
		int count = VERTEX_COUNT * VERTEX_COUNT;
		float[] vertices = new float[count * 3];
		float[] normals = new float[count * 3];
		float[] textureCoords = new float[count*2];
		int[] indices = new int[6*(VERTEX_COUNT-1)*(VERTEX_COUNT-1)];
		int vertexPointer = 0;
		for(int i=0;i<VERTEX_COUNT;i++){
			for(int j=0;j<VERTEX_COUNT;j++){
				vertices[vertexPointer*3] = (float)j/((float)VERTEX_COUNT - 1) * SIZE;
				vertices[vertexPointer*3+1] = 0;
				vertices[vertexPointer*3+2] = (float)i/((float)VERTEX_COUNT - 1) * SIZE;

			}
