What can push a platform sprite besides solid objects? I made this platform game where there is this fan that blows wind and I want that wind to push the player back but the only way I was able to accomplish this is by making another a transparent sprite with the sine behavior and solid behavior and putting under the wind so it pushes the platform sprite back. But now the platform sprite can jump onto the transparent block. So my question is what else can move a platform sprite besides a sprite with a solid behavior?
