Event pass through overlapped sibling sprite

Recommended Posts

I have two overlapped sibling sprites, and they are NOT nested.

const spriteA = PIXI.Sprite.from(...)
app.stage.addChild(spriteA)
spriteA.interactive = true
spriteA.on("pointerdown", () => {console.log("spriteA")})

const spriteB = PIXI.Sprite.from(...)
app.stage.addChild(spriteB)
spriteB.interactive = true
spriteB.on("pointerdown", () => {console.log("spriteB")})

What I want to achieve:

When I click the overlapped area, I want the event on both spriteA and spriteB fired.

I leave spriteA and spriteB NOT nested on purpose, due to some reason they cannot be nested.

This behaviour is not included in pixi package. However, PixiJS team certainly does not have enough exp to implement everything that user wants. Since v5.2.0, you can override interaction behaviour.

Its possible by overriding TreeSearch. https://github.com/pixijs/pixi.js/tree/dev/packages/interaction/src

 "renderer.plugins.interaction.search = new MyTreeSearch();" should solve that, if you code that MyTreeSearch :)

Please share your results, I'll put your version in wiki as a hack: https://github.com/pixijs/pixi.js/wiki/v5-Hacks
