Apply the behavior "Solid" in an image, without the blank pa

Sorry if i ask but i need a real help

I need apply the behavior "Solid" in an image, but without the blank parts

as we see, select the entire image to make solid :/ I wish only the colored parts are solid

Can you help me?

thank you very much

What are you doing to do with all of that in a single image?

To answer your question, you're going to be adding ALOT of collision points. (right click, add point)

Probably a better idea to break that thing up into some more sprites, ex. tree, water, rocks, etc...
