Hi. I need to make an object rotate around another object you know like a shield that spins around your ship in a shooter.

If you have MMF 1.5 then you can download the Orbit Extention. Else you'll have to learn trig

Use the Advanced Math object. Then put in the following events:

>start of level
-set decimal offset(advanced math object) to 3

>always
-add 1 to shield's alterable value A
-set X position of shield to ( X of player+([distance from player] * Cosine(sheild's value A))/1000)
-set Y position of shield to ( Y of player+([distance from player] * Sine(sheild's value A))/1000)

>if shield's value A >360
-subtract 360 from shield's value A

Trig may be confusing. If you can't figure out what the following code does, just plug it in and don't worry about it for now.
