I wanna reduce the hitbox of an actor in order to make it stop from floating. I'm making a game and one of my actors is floating above the ground due to its original size, is there anyway I can fix this from within the code. My code for that actor is:

Insert after line 10: 
setImage(myImage);
If that doesn't work, try trimming transparency from the image (any row of pixels that are all transparent).

Download my Image Transparency Adder/Trimmer scenario. Open it in greenfoot, then close it (to create scenario folder). Use file directory to locate scenario folder. Open folder and find executable jar file within. Run jar file. Load image from your scenario's image folder, then save it.. It will automatically be trimmed. Close executable and resume your project.
