Canvas Size and Positioning

I tried to talk about this in another post, but haven't received a response.

So I have 5 spawnpoints that are the position at where things randomly spawn.

Like this:

That is one of the 5 spawnpoints on top on the canvas.

My question is how do I make sure that the spawnpoints stay proportional to the canvas using the canvas size and position?

Thanks.

 

Anchors. Check out any good UnityEngine.UI tutorial and pay attention to how the anchors affect sizing.

 

The problem is that the spawnpoints have a normal transform not a rect transform

 

This is a common enough question that I finally put it all together to save folks here some time:

- convert mouse position to canvas position
- convert canvas position to world 3D position
- convert canvas position to 2D sprite position (in Z == 0 plane)

Entire package enclosed... it is one directory (CanvasUIToScreen) and contains a scene setup with a 2D sprite at Z == 0, a 3D ball that rolls over a level made of primitives, and a 2D Canvas hierarchy with a marker 2D that tracks your mouse, driving through to the others.

It happens in this order:

- Mouse drives the 2D UI element
- 2D UI Element drives the 2D sprite
- 2D UI Element drives the 3D sphere

Enjoy! Take whatever you need!

 

I saw the package, but am confused as to how it relates to my situation.

 

Based on this statement,

and this statement,

You should be able to use the package I made to get back and forth from canvas to world to whatever-you-want-space, regardless of what transform is on what.

If you cannot, then I have failed to understand what your actual needs are.

 

I really appreciate your help and will understand your code to implement a version of it in my project. Thanks!
