I'm having a NPC that I want to rotate to a waypoint, but I want to do that in a motion, so not with dbPointObject.

Does anyone knows how to do that?

Yeh, keep a variable:

+ Code Snippet

float targetAngle;

This is the angle you want to turn towards but not the actual angle you are facing, then do something like:

+ Code Snippet

if(dbObjectAngleY() < targetAngle)
{
    // turn one way
}
else if(dbObjectAngle() > targetAngle)
{
    // turn other way
}

I got something to work, but now when its rotated it should stop the loop. but now when its finisht whit rotating it first rotating right than left and it goes on like that...

+ Code Snippet

		int X = dbObjectPositionX(NPC);
		int Z = dbObjectPositionZ(NPC);

		int TX = dbObjectPositionX(Target);
		int TZ = dbObjectPositionZ(Target);
		
		int Angle = dbAtanFull( TX-X, Z-TZ );
		if(Angle == 90) { Angle = -90; }
		if(Angle > 90) { Angle = Angle - 90; }

		while(dbObjectAngleY(NPC) != Angle)
		{
			int l = dbObjectAngleY(NPC) ;
			if(dbObjectAngleY(NPC) < Angle)
			{
				dbTurnObjectRight(NPC,1);
			}
			else if(dbObjectAngleY(NPC) > Angle)
			{
			    dbTurnObjectLeft(NPC,1);
			}
			dbSync();
		}
