Can someone tell me how to make a 32 directions rapid bullets engine in TGF?
Oh sweet mary.

that's a rough example, there are some things that you should fix if you want a perfect thing.
P.S. sorry for my mangled english.

You really should have 360 directions for bullets if it's free aiming. It's dead simple:
Set X Position to X Position + Cos(Angle 0-359) * speed
Set Y Position to Y Position - Sin(Angle 0-359) * speed

I tweaked the example a bit : http://www.freewebs.com/appien1/rapid_32_bullets.gam how can i do that you cant see the bullets when they are overlapping the player when they are created?
Oh sweet mary.

..You could actually do it so that it has 360 degrees, just do it with that advanced maths object.

i'll try to explain...
In that example i made there was like:
always: -set alterable value a to direction*(360/32).
This time you don't do that, just set alterable value a to the angle you want it to be. You can do like when pressing a key the player turns a few degrees. Or you can do it mouse-aimed but for that you'll need some other functions and i don't know if they are in tgf.
P.S. sorry for my mangled english.

Mmm sounds hard, is it possible to calculate the angle from the position of the player and the mouse cursor or so?
Oh sweet mary.

Oke I got it it can easily be calculated with Advanced Math Object.
Oh sweet mary.

Yes the angle between 2 coordinates can be calculated with atan or, more easily with atan2, and some extensions have a function for that. I don't remember is it like direction calculator or advanced maths extension or what ever. Anyway, good if it works now.
P.S. sorry for my mangled english.

Angle between two points:
(x1,y1) and (x2,y2)
is
atan((y2-y1)/(x2-x1))
My signature is never too big!!!
