[Trigger] Unit Wave Spawning Help

[RupTure_QS]

So the thing I need help with, is I am having 2 types of units spawn per 30 seconds (a wave), and then an additional unit spawns every 3 waves and then eventually every 2 waves within 35 minutes into the game itself. But I can't figure out how to keep track of wave counting without having to use a ton of if/then/else to say if the wave is on wave 3 then spawn this unit... Help would be much appreciated!

Modulus operation is what you need.

Mod(X,Y) returns the remainder of the integer division of X with Y.

Mod(99,3) = 0
Mod(7,3) = 1
Mod(11,3) = 2

You can test if a wave is a multiple of Y by the comparision...
Mod(Wave, Y) equal to 0

Thus your spawn system does the following (every 30 seconds).
1. Spawn the normal wave units (both types)
2. If wave multiple of strongwave then spawn a strong wave.
3. increment wave (+1)

wave is an integer variable that starts at 0.
strongwave is an integer variable set to 3 initially.
After 35 minutes strongwave is set to 2.

This may or may not cause a double strong wave spawn during the swap over (where 2 consequitive waves spawn the strong wave as a result of the change of spawn period) however that should be a minor bug that is mostly unnoticable. One solution to such a problem would be a counter on the wave type that you reset to strongwave after every time it spawns, but this is considerably more complex. The simplest solution would be to offset the time the swap happens so it is a wave where both rates are a common denominator.

Firstly, you're leaking points. Take a look here: http://www.hiveworkshop.com/forums/triggers-scripts-269/things-leak-35124/

For the additional spawn every 3rd wave, use an integer to count when to spawn.

• Your existing trigger
  • Actions
    • Set WaveCounter = WaveCounter + 1
    • If (WaveCounter Greater than or equal to 3) then ((do additional spawn) and (set WaveCounter = 0))

For your 35 minutes in problem, put those spawning creeps in the same trigger, but add another condition to the if/then/else: a boolean check, with a boolean variable.
Make another trigger with event elapsed time equal to 35 minutes, and all this trigger will do is set that boolean variable to true.

Thank you very much, that helped out a lot, I would've never thought to use the Modulus function lol, but it proved to be very useful.
