Create BackDrop

there is any way to create a backdrop with a event? like if collision x create backdrop on Y

yeah you could have an active version of the object you want to become a backdrop, then when collision x happens "paste" or "add" the active as a backdrop. It's basically like taking a picture of an image and pasting it to the background.

I didnt understood.. i want something like where i click it will create a Backdrop there...

That is what 00J meant. The active object has an option to either paste or add to backdrop. So what you have to do to add a backdrop is this:

* user clicks
- create active object
- set x position of active to xmouse
- set y position of active to ymouse
- active: add to backdrop
- active: destroy

You only create the active object for it to copy itself as a backdrop, and then you destroy it. The backdrop still remains ofcourse :)

ok thanks :D
