Pixi.js: Migration guide v3->v4

Created on 26 Aug 2016 · 7Comments · Source: pixijs/pixi.js

Textures are clamped by default, in v3 they were repeated http://www.html5gamedevs.com/topic/24778-displacementfilter-not-repeating-when-moving-displacement-sprite/

texture.baseTexture.wrapMode=PIXI.WRAP_MODES.REPEAT;

For filters , you have to use mappedMatrix to convert textureCoord to mapCoord, all because of paddings and pow2. Also, use filterClamp uniform to prevent bad things on edges (inputCoord.xy, filterClamp.xy, filterClamp.zw) : http://www.html5gamedevs.com/topic/24347-weird-filterareas-size-on-v4/ , displacement and blur are good examples for that
if you had that piece of code somewhere, remove it. In most cases, pixi-display plugin might be able to help you.

s.position = myPoint; // COPYING ASSIGNMENT! in v3 that was reference
s2.position = myPoint; //shadow sprite , same coord
myPoint.x = 10; //wont work. ha-ha

s.anchor = myPoint ; // DONT do that please! we will fix it later

https://github.com/pixijs/pixi.js/issues/2859 - YEAH, font is deprecated use font-family and all that
TilingSprite works bad with mipmap, and pow2 textures are mipmapped by default. We will fix that issue later, for now just

texture.baseTexture.mipmap=false;

Would we move this to a Wiki page instead of an Issue?

Is Pixi4 actually not understanding comments in shaders source code ?
The new system finds uniforms even when they are commented out...

That is correct, it does not account for comments. You should open a separate bug, and we should not do source parsing and just use the results of the compiled shader instead.
