Non-minified js files don't work and cause errors

[mishawagon]

Hello and thanks for this amazing experiment. One small problem: if I change the js files to the non-minified version to play around, the code doesn't work. For example, if I change index3.html to load index3.js instead of index3.min.js, there is an error thrown in Chrome (below).

webgl.js:96 Uncaught (in promise) TypeError: Failed to execute 'texImage2D' on 'WebGLRenderingContext': No function was found that matched the signature provided. at updateTexture (webgl.js:96) at Object.createTexture (webgl.js:84) at GL.createTexture (gl-obj.js:31) at RainRenderer.init (rain-renderer.js:65) at new RainRenderer (rain-renderer.js:27) at init (index3.js:74) at index3.js:39

The same happens to me, any solutions?

[mishawagon]

I never heard back, and I didn't end up going further with this.

[mishawagon]

Should I close it?

[albertothedev]

Whatever, I wasn't able to get it working even when minifying it with uglify-js.

[mishawagon]

I don't think it's a matter of it wanting the code minified. I think they didn't release the most up to date unminified code. Their most up to date working code is only available as a minified version. So you could use something to unminify their minified code and go from there. Anyway just an idea.

[albertothedev]

That could be it. It doesn't make much sense but it's the only thing I can think of. I would like to try to unminify the code but it looks like it's both minified and uglified so I don't know if a conversion could be achieved.

Maybe it's this fix which wasn't updated on the non-minified files.

@mishawagon calling texImage2D() on updateTexture() function with null data caused this issue.
replace if(source != null) updateTexture(gl, source); at line:12624 will be a charm.

@albertothedev actually non-minified js files should've updated by gulp build after updating original src/index*.js file first.
