[RESOLVED} Dark background, telescope effect

[Joacim Andersson]

In a game I want the character to look into a telescope and I then switch room, where the player isn't visible, instead it only sees part of the room, like a circle and everything else is black. However, this circle should be controlled by the mouse so you can see different parts of the room.

I similar effect is done in King's Quest II: Romancing the Stones, when Graham enters a dark area near the Sharkees, only the area around the player is lit up and the rest is dark.

I know about SetAmbientLight and Region.LightLevel but that doesn't affect the background.

Is there any way I can do this?

EDIT: I solved this by using an object that has a black sprite with a transparent "hole" in the middle. The sprite is twice the size of the room, and I move the object relative to the mouse position. However is there a smarter way of doing this?

Your approach works, and that is totally fine.

Other approach if you need could be to have 5 pieces, one of the center that is the circle or whatever you want and four others that are top, bottom, left and right in a way that they fit the room. You can use overlays and adjust their width and height dynamically while adjusting their position too. It may be a bit more work.

Here is an example that is close, but in this case I didn't had to move, but the "hole" was animated and I wanted to have the rest static

This is the main menu screen of Don't Give Up the Cat, where the cat that is rotating in 3D is the hole.

Thank you, but I think I'll keep my approach.
