Made an example showing how to 'easily' make lights in HWA. It also has code for dynamic shadow casting, but since the Overlay Object isn't HWA'd it runs a bit slow and don't correctly blend multiple lights.

Don't Try to run this in normal MMF since it uses HWA only effects and will therefore not appear correctly.

The reason the unrar'ed file is 7mb is because the flashlight has 32 256x256 images due to rotation not being pasted correctly otherwise.

Awesome ^^

Very nice, this is great!

If you inactivate the Shadow group it runs abut 400% faster on my computer... Want new overlay!

That's really cool and I'd totally use it, if it wasn't because it lags so much D:

I've done some optimization that will limit what is processed and what walls on different tiles that will cast a shadow. With a 320x240 screen I've gotten it almost lagfree with 3 lights.

If only the Overlay could be HWA'd, that would probably solve all lag problems.

If you just want the lights and not the shadow casting you can disable the shadow group, this will make light blending work correctly and remove the lag.

I think the main purpose of this threat is to show how to make the shadowing. In that case, optimizing the shadow effect is a must

I'd so use this all the time if the Overlay object could be fixed ~

considering MMF2 already creates its own 'frame' or image as such it would be nice to incoorperate "draw pixel" and "draw line" etc. features direct into the Frame, as overlay creates its own image on top of the MMF2 frame, using twice the memory and processing power

It could be great to find a way to cast the shadow in 360° (and not in 32 directions).

This isn't exactly HWA but I also made a little lighting engine:

It doesn't support multiple lights though :P
Overlay + some pixel shaders would make this look magically
