Hello! My 2d platformer game is structured like this:

Level03:

  • tilemap
  • player
  • enemys
    –enemy01

The problem is that the player’s script needs to access the tilemap and other nodes.

If I do get_node(‘/root/level03/tilemap’) it works but then the next level04 won’t work.

If I do get_parent().get_child(0) it also works but then I have to remember to keep the same structure all across the levels.

I thought in something like store a variable CURRENT_LEVEL=00 and increase it and then just get_node(level_CURRENT_LEVEL /tilemap) would be perfect but I can’t make it work
Is there any other way to do it?

Thank you!

just my idea not sure work or not but

var map_lvl = 1
var node ="level" + map_lvl

get_parent().get_node(node)

get_tree().root.find_node() i think.

Definitely you can use variables. Like CURRENTLEVEL you used.
There are many ways to do this, it’s about how you construct the program.
An example way to control different levels: Before you start the game, assign which level will lead to which level by using a variable. For example, in level_1, you use lead_to_level = LEVEL_2 where LEVEL_2 is a level scene.
You can also keep all the level scenes into an array if you want.
There are many different ways.
