[SOLVED]Collision between tile maps and sprite

[KnTproject]

Hello,

I have a problem with adding collision to tile maps. As you can see in the image below, I added collision and I used the right name. I saw that different people add the code: .setCollisionBetween(); to their project, but I can't find what that means. What does that exactly mean and does anybody knows a solution for my problem?

Thanks!
