How do I tint the screen?

Hey guys, another question today lol. I am looking to do a "spidey sense" vision, for lack of a better terms. I mainly want to tint everything on the screen except one item, when i hold space. Does anyone know how i could accomplish this task?

I look forward to hearing your responses. Thanks!

You can put the one object on the top layer, in the second layer you can put the *effect* layer, a transparent rectangle with the color of the tint, and the last layer that you put the rest of the object. When you activate the *spider sense*, you set the second layer to be visible, and set it invisible when you deactivate the sense.

You only need one layer on the top for the effect and then use a blend effect such as source atop.

At Start of Layout Set blend mode for Square to Source atop

Every Tick

Key Down Space Turn top Layer visible Move Square to position X Object1.X and Y to Object.1Y

Finally select the layer in your menu and on the info tab on the right set "Force Own Texture" To "No"
