animated tiles.

[Pryme8]

I am working on a tilemap shader for babylon and was wondering how does Pixi handle animated tiles?
Does anyone have the link to the shaders used by Pixi?

really rough demo, but will give you and idea of how I have it set up if anyone has any suggestions on how to add animation support.

PIXI doesn't have tilemaps out-of-the-box. You have to be more specific.

There are animations on shader side for RpgMaker MV, at https://github.com/pixijs/pixi-tilemap , but its made only for RMMV and you have to actually modify that plugin if you want to make better animations.

hmm, Im mainly just looking for ideas on how to handle tiles with animations.  I am thinking of using the last two open channels I have in the texture that I am sampling (blue and alpha are still unused) could control the animations somehow but I am not sure, and honestly think I would need to keep those channels for collisions and event triggers for the management side not the shader.

I was hoping just to see how different 2d engines handle their shaders.

You can use custom shaders with pixi-v4 but its not that easy. 

You need your own renderer plugin: https://github.com/pixijs/pixi-plugin-example . If you name something "myPlugin" , you can specify "sprite.pluginName = 'muPlugin'" and shader will be set.

One more example of custom plugins: pixi vanilla TilingSprite https://github.com/pixijs/pixi.js/tree/dev/src/extras/webgl

If you need batched multi-texture renderer like vanilla pixi SpriteRenderer, that's worse. you need hacks like these:

https://github.com/gameofbombs/pixi-heaven/tree/master/src/base/webgl

https://github.com/gameofbombs/pixi-heaven/blob/master/src/twotint/sprites/SpriteHeavenRenderer.ts

That plugin adds two-color tint to sprites.

If you need a filter, that will render whole container in temporary buffer and applies something to it, better read https://github.com/pixijs/pixi.js/wiki/v4-Creating-Filters

All those difficulties exist because pixi-v4 is over-optimized and some things weren't pushed to public API  Yes, its fast, but you have to learn of pixi architecture before you use custom shaders.
