About the turning entity, I assumed you has assigned an action to it, it would not work without one. Anyway, here is a small action that you need to assign to the entity that is going to turn toward you. You can actually assign it to look at any other entity. The "you" pointer has to be assigned to whatever is going to be looked at. Also, the version of Game Studio is important. Prior to 6.4 "time" was used to correct the time factor for different computers. After that, it was changed to "time_factor". Look it up on a newer manual. (Found in the download area).

Edit: I included a line if(mouse_middle) just to give the option of starting the turn by mouse input. Remove it when it is not needed any more.

This action code works:

Code:

---

action a_turner
{	
	var original_direction[3];
	var new_direction[3];
	var pan_difference;
	var pan_direction;
	var turnspeed = 4;

	while(1) // action goes on forever or entity is removed
	{
		// Check angles
		you = player; // or whatever is going to be turned toward
		vec_set(original_direction,my.pan);
		vec_set(temp,your.pos);
		vec_sub(temp,my.pos);
		vec_to_angle(new_direction,temp);
		
		if(mouse_middle)
		{
			// Turn if needed
			if(abs(original_direction.pan - new_direction.pan) > 1) // only turn if not looking toward player (within +/- x degrees)
			{
				pan_difference = (360-new_direction.x) - (360-original_direction.x);
				if(pan_difference < 0)
				{
					pan_direction = 1;
				}
				else
				{
					pan_direction = -1;
				}
				
				while(abs(my.pan - new_direction.x) > turnspeed)
				{
					my.pan += pan_direction * turnspeed; // adjust angle increment by multiplying with turnspeed
					
					if(abs(my.pan - new_direction.pan) < turnspeed)
					{
					   my.pan - new_direction.pan
					} 
					// edited: added to ensure end to panning
					
					wait(-time_step*0.01); // adjust step speed by multiplying with 0.01 .. 100
					wait(1);
 
					// (use time instead of time_step in Game Studio prior to 6.8) 

				}
			}
		}
		wait(1);
	}
}

cheers,

Now the entities only use pan and do nothing other...

I post my currently action, which controls the enemies. All functions will describe in the comments:

Code:

	var save_pos[3];
	var save_id;
	rolling_kind = int(random(3))+1;
	if(int(random(2))+1 == 1) //set the rotating kind (pan or tilt)
	{
		rolling_dir = -1;
	}
	else
	{

sry, but I are stupid to write a script with the wished function...
