It may be a bug so i'm posting here.
Are they supposed to work together ? How the bug ocurred: Platform and Sine together. Sprite on solid. Sine initially off. When moving activate sine. When sine is activated Sprite is moved , in my case like 100 pixels up. Then it moves according to sine parameters. When sine is deactivated the Sprite returns to original position. Resuming: Sine movement starts at wrong position instead of initial sprite position.
