Hi, I’d like to create a mini game like “Ham il criceto”, but i can’t understand a couple of things.
1-How can I create a collision between the hamster and the grass? I tried with two images (the yellow background and the green grass), one above the other, but it doesn’t work (logically) because the transparent part of the image collides, too.
2-How can the hamster run straight? I can’t use x and y
P.S: I’m sorry for my English 
P.P.S: What is your record?
