BasicGL for Blitz

Thanks "arkon", but I couldn't get it to work.

Anyway, by replacing the While/Wend loop in the terrain demo with the following code, it enables the cursor keys to steer the camera:

While gKeyHit(KEY_ESCAPE) = 0 And gProgress() = 1

	If gKeyHit(KEY_F2)
            	;Polygon mode
    	       	pMode = pMode + 1
            	If pMode > 2 Then pMode = 0
            	gSetPolygonMode Mat_1, pMode    
	End If

	;Move Camera
	newTime# = gGetNewTime() * 50	
	deltaTime# = gGetDeltaTime()
;    	gMove Camera_PV, -deltaTime# * 60
    	x# = gGetX(Camera_PV)
    	y# = gGetY(Camera_PV)
    	z# = gGetZ(Camera_PV)
    	ty# = gGetTerrainHeight(Terrain, x#, y#, z#)
	y# = y# + ((ty# + 20) - y#) * deltaTime# * 10
    	If y# < ty# + 5 Then y# = ty# + 5
   	gSetPosition Camera_PV, x#, y#, z#
;  	gSetRotation Camera_PV, 0, Cos(newTime#/ 4.0) * 60, 0      	      

	If gKeyDown(KEY_UP) Then gMove Camera_PV, -1
	If gKeyDown(KEY_DOWN) Then gMove Camera_PV, 1
	If gKeyDown(KEY_LEFT) Then gTurn Camera_PV, -1
	If gKeyDown(KEY_RIGHT) Then gTurn Camera_PV, 1
