I have pinned a sprite to another sprite position and angle but when i test the game it appears at another position long above it. Why does it do this? I may share my project if you can't help me whit this information.
You probably resized it leaving the image point outside of the image itself. Check the image point. 99% sure that's the problem.
I made it so the pinned sprite increases and decreases in width back and forth constantly. But it doesn't get smaller then it was originally, it just increases in width. Can that still be a problem?
Did you check the image point? Make sure it's in the middle of the sprite. If that won't work, I suggest you to upload the capx.
Develop games in your browser. Powerful, performant & highly capable.
Make sure you are also not pinning an object which is on a different parallax layer.
That may cause some positioning issues as well.
Posting your capx in the first place should actually be a reflex as it ALL depends on how you set up your project.
