Hi folks,
I’m using a set of 8 spawn points for targets to appear at, with the spawn location randomized from a group ‘active_spawn’ (spawn points with no target) and a rand_range which uses the size of the ‘active_spawn’ group as it’s higher limit.
var possible_spawns = get_tree().get_nodes_in_group("active_spawn")
var spawn_range = get_tree().get_nodes_in_group("active_spawn").size()
var random_spawn = possible_spawns[rand_range(0, spawn_range)]
My issue is that once all 8 spawn points are occupied and the group ‘active_spawn’ is empty, any further atempts to spawn a target result in the error ‘Invalid get index ‘0’ (on base: ‘Array’)’ which crashes the game.
Any attempts of mine to add exception handling have had no effect. I’m rather stuck, so would appreciate any insight you’re able to provide! If I haven’t provided enough information/code, please let me know.
Cheers,
Matt
