How does 'Move at angle' work?

i've set up a custom vector that my sprite will work on instead of the normal coordinate grid. only problem is that i don't know how the move at angle event actually works. How do I create this event from scratch without using it itself? With that answered, i can try and implement it into my vector

"Move at angle" moves the sprite instantly (teleports to new position).

If you want to use this action to gradually move your sprite, you need something like this:

On every tick -> Sprite Move 100*dt pixels at angle 45

This will move the sprite at speed 100px per second. Or simply use Bullet behavior.
