Emscripten port

[denzelbro]

createDevice is one of the startup functions so it looks like the irrlicht library for emscripten is not properly build or linked.

Thanks, I will experiment with the compilation.

https://github.com/netpipe/IrrlichtDemo ... emscripten uses codeblocks to make the result very streamlined and easy.

made setup very easy and enjoyable , was thinking about making a scripted app/game launcher also a custom webpage format that is animated and easy to make sites for. please message me if interested in helping.

wasm file was 5 mb

[netpipe]

new demo added, the EMMath http://www.netpipe.ca/apps/math/test.html resulting wasm was 40 mb not sure what changed from the other demos

[netpipe]

i got the EmCPython compile working but when i add
-s EMULATE_FUNCTION_POINTER_CASTS=1 to irrlicht compile it says

FuncCastEmulation::NUM_PARAMS needs to be at least FuncCastEmulation::NUM_PARAMS needs to be at least 1717

Can't say I remember any functions in Irrlicht with 1717 parameters :-)

[netpipe]

https://github.com/netpipe/emscripten-projects a little collection of working libs for emscripten.

[netpipe]

also i have SDL_audio compiled and working for emscripten now http://netpipe.ca/apps/sam/Pong.html

[netpipe]

was able to fix FuncCastEmulation::NUM_PARAMS needs to be at least FuncCastEmulation::NUM_PARAMS needs to be at least 1717 by using latest opengl-es branch of irrlicht.

Not sure when this started happening as I'm on an entirely new PC now and don't have my old one, but Irrlicht is crashing on Emscripten when I remove an element that has children. Here's the stack trace:

Trying to debug it but I'm not entirely sure yet...

EDIT:

So I traced it all the way back to this code:

Code: Select all

ITexture* curTex = ((IGUIImage*)this->b)->getImage();
driver->removeTexture(curTex);

Once I'm done with an image I don't want it sitting in cached memory so I remove it. The webassembly apparently does not like this, but everything else is fine with it (Windows, Mac, Linux, Android, and iOS don't complain)
