System in ECS

[pim]

Hi!

Since Orillusion uses a Data-Oriented Design & ECS architecture, I wondered if there is any documentation on creating your own Systems.

for example if I create a custom script/component called Health and another called Attack; how would I query the entities containing these components?

你说这个吗？
Object3D文档里面有

orillusion 不是严格的 ecs 架构，弱化了 system 的概念，将 system 基本一起放在了 component 里

对于查找 Component，可以参考 object 的相关 API，比如 getComponentsInChild 可以查找一个节点中所有目标 Component

// get all MeshRenderer components in obj
let meshList = obj.getComponentsInChild(MeshRenderer)

类似，可以通过遍历 scene 找到所有目标 components

// get all attack components in scene
let attaclist = scene.getComponentsInChild(Attack)

@shuangliu Makes sense, thank you!
