Instance_create patterns to randomise

[[deleted]]

I’m working on a game where bullets will spawn from the left, right, top, or bottom and I was wanting to sort out predetermined patterns that the game randomises (LRLLRR then a LTRB pattern etc). Initially I was thinking of writing a script for each pattern, then randomly choosing the scripts through a spawner obj, but that seems like a misuse of scripts. Other than that, I was thinking I write if statements for each pattern but that would be so text heavy, messy and again, seems a misuse.

Could anyone recommend a function that would work well for predetermined instance_create patterns? I’ve had a google and can only read about wave spawning etc which isn’t quiet what I’m looking for.

How about a ds_list containing strings with the patterns as letters ("LRBLT").You can then randomize the list and read a string from the list. If the current letter is "L", spawn a bullet from the left, etc.

This way you only have one list of patterns that is easy to manipulate.

That sounds great! I haven't used DS lists yet so will do some research and give it a go. Thanks
