How can i make a appearing platform

Hey guys, i’m pretty new to gdevelop and i need some help.I’m currently making a action platformer but i dont know how to put this certain event

so basically i’m trying to make an event where the player must kill a certain amount of enemy for a platform to appear for them to progress.Any one know how to do that?

You can use a variable to track the kills. Every time you delete an ememy increase the variable. When the variable reaches the set number then add the platform.

I like to use placeholder objects. Just a simple sprite with an X drawn on it. Add it to the scene. Hide it at the beginning and then used it’s coordinates for reference.

A placeholder is nice because it’s visual, you don’t need to copy the coordinates and if you make changes, all you need to do is move the placeholder.

You could also hide the actual platform. Just be sure to disable the platform because hidden objects can still be interacted with.

There are infinite ways to do things.
