How do I set correct bullet angle of motion?

I have my character pinned to a rotating platform and has bullet disabled until key is pressed. On key press/tap, how do I set the angle of motion of my character to go away from the platform? Thank you!

I unpinned and enabled bullet on tap and set angle of motion to angle(platform.x,platform.y,character.x,character.y) but its still not working correctly.

Trying to move like barrels in donkey kong?

So, because an object lying flat is technically at 0 degrees, when you want your character to fly off perpendicularly, you actually want to travel at -90 degrees, or 270. So rather than set the angle of motion to that angle, you want [RotatingObject.Angle-90]

Here's a .capx that does, I think, what you want.

-90 = 270... gotcha. Thanks!

just like up down left and right

Right = 0

Left = 180

up = 270

down - 90

down is simple "90" not "-90"

sorry typo should be Down = 90
