Feedback Add Confine Screen Edges To Perspective Cameras

It would be really helpful to have the ability to utilize

Confine Screen Edges

for a perspective camera.

I had a look at this post https://forum.unity.com/threads/perspective-vcams-with-2d-confiners.508804/ and it detailed how it might be difficult to make this work in a general sense.

I wen't ahead and did some brainstorming and thought up a way that I think would work fairly well and wanted to get some feedback / input if it might be possible.

A

Confine Mode

could be added named

Confine 2.5

this mode would allow a

BoxCollider2D

to be added as the

Bounding Volume

. Essentially with this mode checked it would be equivalent to the

Confine 2D

with

Confine Screen Edges

checked but for a perspective camera.

We could then take the position in world space that the

BoxCollider2D

is at and use that section as the point in our perspective camera to check for camera edge collisions.

This is pretty hard to describe so I drew something to describe what i'm talking about and attached it below. Would love to get thoughts here.

 

Ah sorry I think I finally had a better understanding of what you meant in the original post.

I went ahead and made some modifications to the Confiner script. I was wondering, would you be interested in me making these modifications a bit more full fledged and pull requesting?

The way I have it working is essentially you utilize a BoxCollider2D along with Confine Screen Edges and a variable (float) for the perspective camera depth. I grab the orthographic size at the perspective camera depth specified in the variable and confine the camera edges at that depth to the box collider specified.

 

Another quick note here is i'm having a hard time finding how i might grab the gate fit property from a cinemachine extension / cinemachine in general.

Any advice as to how i might grab this?

 

I was thinking the same thinking about the BoxCollider2D z coord. However I was thinking that having it as an extra parameter would allow for a greater degree of control.

Now that I think about it though it might make more sense from a usability stand point.

As for the gate fit property ultimately I ended up grabbing it utilizing this bit

CinemachineCore.Instance.FindPotentialTargetBrain(VirtualCamera).OutputCamera.gateFit;

 

Hello @Gregoryl , I apologize for necroing this thread, but having an option to confine perspective cameras to screen edges would be a really useful feature to have in the core Cinemachine package. My current project is a 2D platformer metroidvania (ofc it is...) and I would like to have a nice 'natural' z-based parallax effect on my maps, without resorting to dodgy tricks and scripts that end up constantly moving the position of gameobjects to account for camera position. The ONLY reason why I ended up not implementing it, is because Cinemachine won't stop at the map screen edges like an orthographic camera would, which is unfortunate cause otherwise the parallax effect works beautifully (most importantly, is very 'controllable') and it's something that could 100% be managed by the map designer.

Are there any plans (if any at all) to implement such feature? Cinemachine is such an amazing product in general, that It seems really odd having third party assets providing this feature out of the box, while Cinemachine still can't (or won't).

Sorry to drag @Meatloaf4 in this, but did you have any success with your implementation?

 

Hello there,
Sorry for diggin out this old thread but I thought it would make sense to ask if there is any news about screen edges confinement for 2d perspective camera

Also, if @Meatloaf4 worked some magic, it would be greatly appreciate if you can give us any insights !
=)

 

Good to hear Gregoryl ! Thank you as always for your quick reply
Just to be sure, do you mean it will in the next upgrade, or is it already out ?

I'm running Cinemachine 2.7.1 on unity 2019.3.9, do I need to upgrade any of those ?
