Casting Shadows in C2

Hi there,

I'm new to C2 and have been playing around with it a bit over the last couple of months. I've created a couple of dynamic lighting/shadow casting tests with it that I wanted to share.

<img src="http://www.adamduncan.com/LightingTest/screen.jpg" border="0" />

The first is a shadow casting example (looks and runs best with a WebGL enabled browser), drag the circle at the centre of the light around to see the effect: adamduncan.com/LightingTest.

The first demo is pretty processor intensive (ideally needs to be run in Firefox or Chrome to see the effect at its best) and neither example has be optimised or anything. I was just playing around to practice with C2.

Any feedback is welcome.

Apologies for the complexity of it. I've since discovered a good example done by R0J0hound in this thread: scirra.com/forum/dynamic-shadows-now-possible_topic56174.html. I recommend looking at it as it is much cleaner and nicer than mine (didn't see it until after I'd done my examples).

Also, many thanks to R0J0hound for creating the canvas plugin that made these examples possible. To run the .capx files you'll need to download it from: scirra.com/forum/plugin-canvas_topic46006.html

I used the 'insert hyperlink' option for the post above, for some reason it didn't work and just posted the full url. Sorry about that, it also seems to have deleted the sentence with the second example in. Obviously I'm doing something completely wrong (I don't post on forums much). I'll try to post the flashlight example here: adamduncan.com/Flashlight.

Really nice! Any plans for using this in a game?

looks really good

Impressive! is this a custom webGL shader or something else?

Looks cool, I was wondering the other day how i'd do something like this. Any hints? :P

amazing effects =)

Very, very good ! Maybe you can provide the capx ? :)

That's cool! I can see this getting some real use in some of the RPGs people are designing, for street lighting or day/night cycles.

Very impressive dude. <img src="smileys/smiley4.gif" border="0" align="middle" />

The 3D feel is astonishing !

The LightingTest looks nice, but not that much realistic...

How come the shadows appear only when the light get closer?

Also have you ever seen real life shadows getting darker as two overlaps? o_O

The Flashlight one looks good though

I imagine putting the shadows on the same layer and changing the layer transparency will fix the overlap issue.

we can all agree that we would like to know how to do this...

Impressive, very nice ! good job.

Nice, can it handle multiple light sources ?
