Help create Obi handle on script at runtime

[Richard]

Hi,

In Unity, implementing things for the editor and for runtime (play mode) is often radically different. The editor uses immediate mode GUI, while at runtime you generally use Unity's UI system. Both work in completely different ways, so yes you can implement marquee selection for either purpose. You don't have to use the one implemented in edit particle mode. I already gave you two links with examples, both implement marquee selection tools in different ways and none of them needs Obi.

So you need to think about whether you want to implement this for an editor tool, or for a game/application. It is not entirely clear to me what you're after.

Hello.
It is for a game/application.
