I am creating a custom portal and I want it to act similar to a nether portal. I have created an overlay that is painted on screen when you stand in the portal but I need to create the camera warp that happens when you are standing in a portal and I cant figure out how to do this. Any help is appreciated!

Not my area of expertise, but it looks like the NetherPortal code is "spread out".

First you have NetherPortalBlock.entityInside() that sets the isInsidePortal flag for the entity.

Then you have LocalPlayer.handleNetherPortalClient() that controls the timer.

 

The timer is then used in

GameRenderer.render() for renderConfusionOverlay(),

GameRenderer.renderLevel()

and (Forge)Gui.renderPortalOverlay()

I'll leave it you to decide how much of this you can reuse.

 

The latter is what you should be overriding for your overlay, see for example: https://forums.minecraftforge.net/topic/115993-how-to-remove-the-sight-cross-in-the-center-of-the-screen/#comment-512655

except you want VanillaGuiOverlay.PORTAL and to actually draw something, not just cancel the event.
