Pixi.js Renderer in Proton.js - Prevent clearing screen

[GrodanBoll2000]

As title says, I'm using the Pixi Renderer of Proton.js. I want to have the effect of not clearing the screen after every draw call, just like when I turn preserve drawing buffer to true (and renderer.autoClear = false;) in the WebGL renderer.

There's nothing like that for the Pixi renderer when I look into the Proton.js source code. I've isolated the Pixi renderer part of the Proton.js source code if someone can help me find what to change/add in order to achieve the effect i want.

Thanks.

http://pixijs.download/dev/docs/PIXI.WebGLRenderer.html its called clearBeforeRender. However i do not have guarantees that it works on iphone and some other devices. even on PC's it can be a problem. If you see it, try using temporary RenderTexture and render to screen from it. This is different topic and it will require from you proper research in pixi-examples repo

Thanks for your response. I got it to work by changing not the code i linked but instead, changing in the pixi.js file.

There are problems for Safari though, background is flickering like crazy between red and black even though the background should be black only (works in the other browsers). The particles moves fine till they are dead, then the drawn trace that is preserved starts to flicker like crazy a few pixels from its position to its previous position whatever direction it came from. Any ideas of how to solve or is there a better way to do draw feedback?

Thanks.

It switches between multiple framebuffers, nobody knows why. Time to dig into RenderTexture  tricks
