Random button trigger

[Nikkone]

I've been working on this but I guess it's safe to say I'm clueless with it

Say theres a tavern with a Footman, grunt, and ghoul. How do I make a random button to select any one of those at random?

And how do I make a game mode, -ar? (Self explanitory)

Create one item with no gold cost or lumber cost and a unit owned by all players nearby with Inventory ability. Now, check when the item is bought:

• Trigger0
• Events
  • Map Initialization
• Conditions
• Actions
  • Set Units[1] = Grunt
  • Set Units[2] = Footman
  • Set Units[3] = Ghoul

• Trigger
• Events
  • Unit - A unit acquires an item
• Conditions
  • (Item-type of (Item being manipulated)) Equal to Random Hero
• Actions
  • Set Point1 = (Position of (Triggering unit))
  • Unit - Create 1 Units[(Random integer number between 1 and 3)] for (Owner of (Triggering unit)) at Point1 facing default building degrees
  • Custom script: call RemoveLocation (udg_Point1)
  • Item - Remove (Item being manipulated) //Optional

Units[] is a Unit-type variable.

As Pharaoh is saying that only variables that have arrays can be executed randomly like in weather generation, in playing sounds and etc.

If you were using JASS then you would have the unitpool type available to you, which basically handles exactly what Pharaoh_ has done.

• Unit - Create 1 Units[(Random integer number between 1 and 3)] for (Owner of (Triggering unit)) at Point1 facing default building degrees

Which trigger is that and what function?

 

[Pharaoh_]

Unit - Create unit action.
When it asks for the Unit-type (the default footman) go up and tick the "Variable" 'Units' you created. Units is an array-enhanced Unit-type variable. If you need more info, go to the Tutorials section.

Edit: Nevermind it works fine. +Rep, thanks.
