I have game here.

can someone tell why player overlaps objects, even if they have solid behavior <img src="{SMILIES_PATH}/icon_e_confused.gif" alt=":?" title="Confused"> ?

(ps. i made those images. no copying, plz.)

I presume you are talking about the character standing in the block?

This is because you didn't set your collision polygon. Its these little dots that you drag out to the edges...

I made the sprite a little bigger(more clear space and dragged it out a fraction) you need to do same for rest i.e character doesn't have a barrier, only on left.

This is the solid barrier that cannot be crossed so to speak.

Oh. I didn't know this thing. I have made games year now... and thing like this looks so basic! Thank you
