ok.. this whole app works fine. menus, panels, world setup..eveything... in startworld() we hide the PANELS since we are done with the main menu at that point.

We also do this in startworld():
Code:
	while(player == NULL) { wait(1); }
	player.x = 570;
	player.y = -1996;
	player.z = 330;
	player.pan = 323;
   vec_set(camera.x,vector(-180,0,50));
	vec_rotate(camera.x,player.pan);
	vec_add(camera.x,player.x);
	camera.pan = player.pan;
	camera.tilt = -15;


That lines up the camera PERFECTLY behind the player in a third person cam type arrangement (above and behind). Now the thing is in the AUM61 code I got the vec_set thing from the player action enters a while(1) wait(1) of course and handles his movement and gravity. again.. works like a dream.. however.. when we place those 3 magic vec_??? lines from startworld():
Code:
vec_set(camera.x,vector(-180,0,50));
	vec_rotate(camera.x,player.pan);
	vec_add(camera.x,player.x);


which should (AND DO) keep the camera at its perfect 3rd person cam alignment. Thing is when I do this in the player action (or even the main loop instead) or anywhere that updates it constantly i get grey(my sky.tga color actually) flickering... so I figure the camera is going apeshit and I hit F11... bingo.. the cam is flickering thru two or more x,y,z positions and I realize the camera is being set to the vector (1 position move) rotated to match up with pan (2 moves) and added to player vector (3 moves) so I do what anyone would do and make a tempvar and do all the calcs on it behind the scenes then once I got the resulting vector copying it straight to camera vector with vec_set(camera.x,tempvar.x) well.. it works... but it still flickers!!! grr!! which is really wierd cuz in that scenario is like "wtf else is moving the cam then?" anywho.. here is the whole code and I'll totally sex0r anyone who can figure it out.
