png images and tranparancy

I've tried to make a simple plate forme game with the tutorial: how to make a platform game

but, as for the ground, I've use different forms , where there is some form with parts of transparancy.

like this:

As in the game, it's like this:

As you see, it's a little bit incontinente to have the part of transparence feeled

Could anyone please tell me how to handle it, thanks

Not sure what the problem is! In the image, it looks fine...

in fact, my person can not contact directely the ground...because of the part of image transpant...is it possible to touch the ground <img src="smileys/smiley1.gif" border="0" align="middle" />

,like this:

image example

sorry, but i don't know how to upload this image

you're talking about a collision mask, you can edit it in image editor by clicking the collision mask button on the left (below the hotsopt button). image is just an image, collision mask is the thing that's responsible for collisions :)

check the manual about this topic here

Wow, Thanks a lot Mark4Media and Ranma, That's really cool

yeah its important to remember that collision and transparency are two totally different things with c2. Transparency is strictly for letting images have "missing parts" it has absolutely nothing to do with collision

Its also important to remember that collisions cant have "holes" in them. They have to be a solid filled shape
