Rotate a Entity slowly to face another

| In my 3D space game, I have some ships attacking other ships. What I have difficulty is rotating the attacker ship slowly over several seconds to face the target ship. PointEntity is too dramatic and unrealistic. I can get the Yaw of each, but that does not offer me a solution. Any one have a solution? Thanks Teff |

| There is some code in the aechives that does this exact thing. not sure exactly where though. |

| Thank you very much! I managed to use the function and modify it so the entity turns in a incremental manner. Works very nicely! Teff xdiff# = EntityX(id)-EntityX( target) ydiff# = EntityY(id)-EntityY( target) zdiff# = EntityZ(id)-EntityZ( target) dist#=Sqr#((xdiff#*xdiff#)+(zdiff#*zdiff#)) pitch# = ATan2(ydiff#,dist#) target_yaw# = ATan2(xdiff#,-zdiff#) shooters_yaw#=EntityYaw(id) If shooters_yaw# > target_yaw# Then TurnEntity id,0,-1,0 If shooters_yaw# < target_yaw# Then TurnEntity id,0,+1,0 MoveEntity id,0,+Cos(sinvalue)*10,speed# |
