plz, let me know how make follow camera in infinite Y-axis game.

First of all, I’m not used to English, so I can’t speak well using a translator. Please understand.

I’m making a game with Gdevelop (of course). It’s a 2D top down view, random generate tile, and like “CROSSY ROAD”, you get points as you go up line by line.

What I want is that if the camera goes up above a certain space shown on the screen with the x-axis fixed, I want the camera to follow it, but I don’t know what to do with it. If you fix the camera, the character won’t move.

If you could show video of some game that use same camera you want then that would help

Cause i do not get your question?
You want camera to move only up on Y axis but don’t go down?
Or you want camera to be able to always go up but only little down to block player?
Or you want player to be blocked from going down beyond camera view?
This but not isometric?

Do you want to implement a “continuous vertical scrolling camera”?
Sorry, this is unclear :

Instead of “if the camera goes up” : do you mean : if the player goes up?
if so, you can use an object (like a rectangle) and detect a collision with your player to move the camera.

Or just give the camera some speed by changing its Y position (you’ll have to move the character too).
Something like this :

Sorry if it doesn’t anwer your question at all!

I’m going on the assumption that you meant is " if the player goes up above a certain space". In which case, something like this (change 100 to the Y position that causes the c camera to move):
