You can rename image points and then call them specifically in your events and actions.
Can you give me an example of using a specific image point for mirroring a sprite and another image point for the pin object? Basically I have a hero, which has a gun attached to it. I want an image point for the hero's hand to hold the gun, and another image point at his mass center for mirror effect. If I use the image point on the hand to mirror every time I change direction it looks like the hero walks a bit, the mirror only works properly with the image point on the center, but both the mirror and pin work using the origin.
