• I have a map with 9 spawnpoints, and 3 enemies. When i die i want to spawn at any of those points based on the distance to those enemies. Preferably the safest one furthest away from any of these. I know how to get the distance between a spawnpoint and an enemy, but only for one instance of each.

for example.

for each spawnpoint

distance(spawnpoint.x, spawnpoint.y, enemy.x, enemy.y) - will only get me the distance to one if the enemies. or is there any way to specify which of the enemy instances i want the distance to?

how do i get the distance between all of them?

• you can use the "nearest/furthest" action in the spawn point object.

• Locale variable "CurrentBiggestDistance"

Locale variable "MostFarUID"

OnDeath

------for each spawnpoint

-------------for each enemy

------------------------distance(spawnpoint.x, spawnpoint.y, enemy.x, enemy.y) > CurrentBiggestDistance : Set CurrentBiggestDistance to distance(spawnpoint.x, spawnpoint.y, enemy.x, enemy.y) AND set MostFarUID to enemy.UID

-------Pick spawnpoint UID= MostFarUID : Spawn Player

-------[No condition] : Set CurrentBiggestDistance to 0 AND Set MostFarUID to -1

Thanks both. i managed to make crossover between both solutions, marking any spawnpoint with no enemies within a range as safe, then spawning at a random "safe" spawnpoint.
