how to use for loop in Update function properly ?

This is a script of mine and if I use it like that a huge amount of crawlers get spawned (it should only be as much as in the maxenemies value).

I think it is probably because the for loop gets called several times before the first one makes the fighting = true, which should end the for -loop.

My question is how to fix that.

Typo?

 

if n==maxEnemies then

[Rick]

for n=0,self.maxEnemies do

if self.fighting == true then break end

if n==maxEnemies then

self.fighting = true

break

end

local b=Math:Round(Math:Random(0, 6))

self.spawners[b].script:SpawnEnemy(b)

zombiesleft = zombiesleft +1

end

end

 

This doesn't really make sense. The if statement to check if n == maxEnemies is kind of useless given your loop goes to maxEnemies anyway. That means your for loop will stop once it hits maxEnemies anyway. What are you trying to do here again? What's the goal?

for n=0,self.maxEnemies do

if self.fighting == true then break end

if n==maxEnemies then

self.fighting = true

break

end

local b=Math:Round(Math:Random(0, 6))

self.spawners[b].script:SpawnEnemy(b)

zombiesleft = zombiesleft +1

end

I want to spawn enemies in the world, and maxenemies is increasing every round.

The goal is to make it actually work fluently and in the later state of developing the enemies are resetted every 3 rounds but they also got more hp.

You'll have to define what "more fluently" really means. What are your exact requirements for this?

Always when theres a new level , the maxzombies value is increasing by 30%,

When theres a new level the for loop gets called once and spawns the enemies.

I put this in the updatwphysiscs function so the program always updates if its time to spawn new enemies or not.

The new map function gets triggered when fighting == false.
