How do I shoot a bullet properly?

the bullet (sprite3) is shot forward but not in the correct position and I can't understand why.

I set the angle of motion at '90, the image point and origin point are at bottom of the bullet

By convention, your images should all point to the right since 0 degrees -- the default angle -- points in the same direction. I suspect that the bullet image you have currently is pointing up.

so what's the thing to do in this case?

Rotate the the bullet image -- not the sprites themselves -- so that it points to the right. Make sure you reposition your image points accordingly.

If linkman2004 help didnt work u can disable set angle in the properties

or enable it ... just toggle it
