Im making a Tower defence but have problems with the waves spawning.
Problem: I want the next level of creeps spawn 30 seconds after the previous wave has died. i cant get it work. the only way i can get a wave spawn after another to is to set time elapsed 30 secods, 60 seconds 90 seconds and so on. I think that way suck but i really want this to work! please help me!
 
There's two ways you can do this.

1.
Trigger:
  • Spawn
    • Events
      • Time - Every 30.00 seconds of game time
    • Conditions
    • Actions
      • Set SpawnPoint = (Center of Spawn Region <gen>)
      • Unit - Create 1 Footman for Player 12 (Brown) at SpawnPoint facing Default building facing degrees
      • Custom script: call RemoveLocation (udg_SpawnPoint)


2. Create a unit group variable, and as you create all the units for the wave, add each of them into the unit group. Then with an on death event trigger, if the unit is in the unit group remove them and then run a check next level trigger (checking conditions). If the number of units in the unit group is 0, then you can wait 30 seconds action, and run your level trigger which spawns the next units.

If you want to use the second one, and need help with the trigger, just reply once more and I can show you the basics.
 
Trigger:
  • AA
    • Events
      • Time - Elapsed game time 30.
    • Conditions
    • Actions
      • <your unit creation here>
      • Set ug = (Every unit in Playable map area owned by <player>)


Trigger:
  • AA
    • Events
      • Unit - A unit dies
    • Conditions
    • Actions
      • If (all conditions..)
        • If - Con
          • (Number of unit in ug) Less than 1
        • Then - Actions
          • Turn on <second wave>
          • Timer - create a time lasting for 30 seconds (one-time)
          • Set TimerVar = (Last created timer)
          • Custom script: call DestroyGroup(udg_ug)
        • Else


Trigger:
  • AA
    • Events
      • TimerVar expires
    • Conditions
    • Actions
      • <repeat everything from Trig 1>


NOTE: THis leaks..
 
He means it creates memory which isn't cleaned up. Eventually the map will start to lag and cause server splits if there are enough 'leaks'. However, back to the question at hand.

I don't have me WE with me, but instead of making that timer and the third trigger, just use the wait 30 seconds function and then do the actions. Clears up some complication and prevents the leak he was talking about.
 
First, set Variable(mine will be called S for Spawn)
Trigger:
  • S
    • Events
      • Time - Every 2.00 seconds of game time
    • Conditions
    • Actions
      • Unit - Create 1 Footman for Player 1 (Red) at (Center of (Playable map area)) facing Default building facing degrees
      • Set S = (S + 1)

Trigger:
  • Turn On
    • Events
      • Time - Every 3.00 seconds of game time
    • Conditions
      • S Equal to 30
    • Actions
      • Wait 10.00 seconds
      • Trigger - Turn on Spawn2 <gen>

Trigger:
  • Spawn2
    • Events
      • Time - Every 2.00 seconds of game time
    • Conditions
    • Actions
      • Unit - Create 1 Footman for Player 1 (Red) at (Center of (Playable map area)) facing Default building facing degrees
 
General chit-chat

  • No one is chatting at the moment.
  • Ghan Ghan:
    See how we like that.
  • The Helper The Helper:
    I do not see a way to go past the 1st page of posts on the forum though
  • The Helper The Helper:
    It is OK though for the main page to open up on the forum in the view it was before. As long as the portal has its own URL so it can be viewed that way I do want to try it as a regular forum view for a while
  • Ghan Ghan:
    Yeah I'm not sure what the deal is with the pagination.
  • Ghan Ghan:
    It SHOULD be there so I think it might just be an artifact of having an older style.
  • Ghan Ghan:
    I switched it to a "Standard" article forum. This will show the thread list like normal, but the threads themselves will have the first post set up above the rest of the "comments"
  • The Helper The Helper:
    I don't really get that article forum but I think it is because I have never really seen it used on a multi post thread
  • Ghan Ghan:
    RpNation makes more use of it right now as an example: https://www.rpnation.com/news/

  • tom_mai78101 tom_mai78101:
    I will have to get used to this.
  • tom_mai78101 tom_mai78101:
    The latest news feed looks good
  • The Helper The Helper:
    I would like to see it again like Ghan had it the first time with pagination though - without the pagination that view will not work but with pagination it just might...
