how about this:

let's say your gun, cannon or whatever can be rotated 360 degrees. Then at some angle the player may shoot.

Now do this:

if firebutton
 force_x#=sin(angle)*speed#
 force_y#=cos(angle)*speed#
 bullet_x#=gun_x#
 bullet_y#=gun_y#
endif

bullet_x#=bullet_x#+force_x#
bullet_y#=bullet_y#+force_y#

drawimage bullet, bullet_x#,bullet_y#
