[behavior] pixel collide

Test pixel overlapping between sprite and R0J0hound 's canvas.

see this demo first

• drag to draw circles on the canvas
• red ball will bounce off and erase some pixels while overlapping any pixels on canvas

Document, behavior and sample capx are included.

Is it made to work with just R0J0hound 's Canvas, or can it be used to test for other objects that don't have the condition?

Nice idea btw.

Just for R0J0hound 's Canvas plugin, which is the only one canvas plugin in C2.

Nice work rexrainbow!

Must the canvas start from 0,0 coordinate for it to work properly though? I find that setting the canvas to e.g. 0,10 or dynamically during run-time after deleting the current canvas makes the "is overlapping/on collision" out of sync.

Also, any chance for the pixel collision to work on moving canvases? Many thanks!

Update

Fix bug while canvas object is not a (0,0).

Please download this behavior again, and try this test capx.

Beautiful!! I've just ran it. The sample capx looks wicked! I imagined the hulk on rampage! CPU went up but i guess it was fairly reasonable. It dropped down as soon as it cleared its path.

Anyhow, I think this should be one of the default behaviors built into C2 along with R0J0hound's Canvas.

Speaking of canvases, do you think you could also look into Pode's SVG Canvas Plugin? Or perhaps come up with a better SVG support? Cheers!

I had no plan for SVG html element recently, sorry.

hey rexrainbow cool stuff. I tryied "push out" action, but it does not work

Update

Fix bug of "action:push out". ( tested capx)

Fixed, please download it again, and thanks for notification.

Update

Add property "Sample rate", which is a sample rate of point for overlap testing.

Set to 0.01 will have less overlap testing then 0.1, see the "Max check count" value in debugger panel.

cool, thank you too!
