How do I show collision masks while in preview?

How do I...?
1

Where can I find the option to see the collision mask during Preview, if there is a function?
If not, don’t ignore it, tell me and close this topic.

It’s in the Debugger Tools section.

Edit: And if you only want to use it while in preview, and have it automatically excluded in your exported versions, there’s a condition for that, too:

I can’t find it anymore. Any idea how to show collision boxes in the preview mode in 2025? Thank you!

It’s still in the same place, here’s the path to get to it.

It shows up in the event sheet when you add a new action

Only seeing your answer now. How could I use gdevelop so long without knowing about this basic functionnality… thanks so much :v:
