Hi, can someone please help me adjust the code.
I’m trying to spawn more than one unit from a building
I have a UI setup where you click on the button (via event trigger)
right now it works but it spawns one random unit from two update functions
I couldn’t figure out how to edit the “ProduceUnits” function to include more than one unit so I duplicated it.
I realize that it’s a backwards way of doing it but I’m new to coding (just started from 0 one month ago) and just trying to stitch stuff together the best I can.
I basically just want to click the button, spawn queue to start the count down and then eventually spawn the unit
This is a script I followed from a course, and I’m just trying to tweak it to suit my project
Sorry if this isn’t the place for this question, point me in the right direction, please!
this is my code for UnitSpawner:
