For a while I was using a sphere as the main character for my game but when I switched it to an actual character model I ran into a problem. When I have my person move right I naturally want them to face right but the only way I can think of having them face right is to rotate them using the “rotate object” command. While this may seem simple it gets much harder when you have to find the angle that you should rotate it from every other direction. For example if the model was facing down and you wanted it to turn right then you would have to rotate at a different angle then you would if it was facing left and you wanted it to turn right. Basically I asking if anyone could give me some code that will face my model in the direction it’s going. Thanks

Just use the rotate objec command untill you get the character facing the right way, then use the command...

set object pivot objnum

That command will lock the object to that rotation.





Hope that helps.

I am assuming you are using newxvalue and what not to come up with your new x,y,and z coords? If so why not just put something like

x# = newxvalue()
y# = newyvalue()
z# = newzvalue()

point object playerobj,x#,y#,z#
position object playerobj,x#,y#,z#

That's not actually the case - the rotate object commands are absolute rotations using world coordinates - put simply, if you say yrotate object obnum,90 - it will always face to the right. It is the 'turn object' commands that are relative to the current orientation.

By the way, it's 'fix' object pivot.

If your character is only moving in two dimensions, then its pretty simple.
if rightkey() then yrotate object 1, 90
if lefkey() then yrotate object 1, 270
if downkey() then yrotate object 1, 180
if uptkey() then yrotate object 1, 0
