I have a sprite with bullet behavior and its angle of motion is set to another sprite that I would like to share the same X Y coordinate with. Like this:

Set bullet angle of motion to: angle(Sprite1.X,Sprite1.Y,Sprite2.X,Sprite1.Y)

Set bullet speed to: 100

And I set Sprite1 to destroy when they both suppose to share the same X Y coordinate, but nothing happens.

Thanks!

Bullet doesn't move with pixel precision. You can't just compare x and y of both sprites. Use distance() expression to check if two sprites are close enough, or Line Of Sight behavior with a very small radius, or collision with small collision polygons.

Note, that if Bullet speed is fast and/or fps is low, then your sprite may travel big distances between each tick and it may actually miss/skip the point where it overlaps another sprite.

That's why I recommend not using Bullet at all. Try MoveTo addon, it's much better suited for this task:
