[CrackedPixel]

Examples needed an updated Makefile

[raysan5]

@CrackedPixel Thanks for the review!

[CrackedPixel]

shapes_splines_drawing:

Is the bezier supposed to break like this when using hard angles?

[raysan5]

@CrackedPixel I'm afraid it is, there are no mittens or circle segments implemented/enabled, it will require a review of all spline drawing functions...

Outstanding items:

• audio_stream_effects: Is it intentional that the delay lowers the volume, or should this be fixed?
• core_input_gamepad / core_input_gamepad_info: Someone with an XBOX controller should double check this
• core_input_multitouch: TBT on mobile
• rlgl_compute_shader: Someone more experienced needs to look at this one. It's something in the shader, all of the other logic is working properly
• shaders_deferred_render: Someone more experienced needs to look at this one. The lighting is not correct
• PNGs need updated: Will be done in bulk via a single PR once the other things are merged in (so that the newer PNGs reflect the changes)

Everything else has a PR open to be fixed. Only 2 examples were broken, which is very good considering some are from raylib v1.0

• audio_stream_effects: should be probably fixed.
• rlgl_compute_shader: are you compiling raylib for OpenGL 4.3?
• shaders_deferred_render: no idea...
• PNGs: I prefer them being updated with the updated examples, not separately

[Peter0x44]

shaders_mesh_instancing only works for web if you compile raylib for with GRAPHICS=GRAPHICS_API_OPENGL_ES3 and compile with -sFULL_ES3. Instancing is a webgl2/gles3 feature.

Currently it is broken on raylib.com, but it would be nice to have it working. I'm wondering if compiling all of the examples for webgl2 could have some compatibility implications, since I don't think it would be easy to single this one out in the build system and rebuild raylib again, just to provide it for this one example.

Or maybe it's not too much hassle to compile this one example separately.

[raysan5]

It seems most of the examples work as expected. I'm closing this issue, I think it's better to open separate issues for non-working examples.
