Question

I am trying to get the enemy to respawn in a random location every time they die, also if i could get it to spawn multiple enemies at the same time that would be great. the enemies are in the same scene as the map if this is needed. Sorry if this is obvious, i am very new to godot.

In the function that causes enemies to respawn, I would add some code that randomizes the respawn coordinates.

To respawn multiple enemies at the same time and/or place, I would store dead enemies in an array, then make the respawn function respawn multiple of them at once. For that, the respawn code should be ‘outside’ of the enemies, not in their script.

I will get right on it! Thanks for the tips!

Create an instance for your enemy.

Add the instance to the scene tree.

Change the global position of the instance to your desired spawn point.

5

Is there an easier way i can have it choose between to values so the enemies can spawn between any point between (-26, -79) and (41, -79)? or do i just need to put every value between those for it to choose from?

You can use randi_range() to pick random integers within a range, or randf_range() for floats.

Thank you so much for the help!
