How do I set the value of a variable by typing something?

[Frostbarge]

For example if I type "-value 300" it'll set the value of a variable(Let's call the value "Damage" in this case). So if I type "-value 2" it'll set "Damage" to 2. I've never been good with triggering commands. Help would be appreciated.

You mean this ?

• Untitled Trigger 001
  • Events
    • Player - Player 1 (Red) types a chat message containing -value as A substring
  • Conditions
  • Actions
    • Set Damage = (Integer((Substring((Entered chat string), 7, (Length of (Entered chat string))))))
    • Game - Display to (All players) the text: (String(Damage))

Um, how did you make the first action? The one which 'Damage' is set to.

Um try yourself before looking in this... its prety easy...

Damage is integer variable
Conversion - Convert string to integer > Substring > Event response - Entered chat string / 7 / String lenght > Event response - Entered chat string

Create variable
Type: string

Whee

You should at least explain to him what's the use of that Action here and there



Ok, here's the thing
By using Substring function, you will have to put 2 values inside it

Example: Player - Add (Integer((Substring((Entered chat string), 1, 5)))) to Player 1 (Red) Current gold

What is meant by numbers 1 and 5 in there, is their position of letters for the words

Okay, let's say we follow the example of 1, 5

When I type "-gold 300", it will only take the value starts from first letter (1) until 5th letter (5)

So, if you set a variable, the variable will set a "-gold <space>"

Spaces also count as a letter, so if you want a -gold 300, to add 300 gold to your player, just

Player - Add (Integer((Substring((Entered chat string), 7, 9)))) to Player 1 (Red) Current gold

So, it will take the 7th letter until 9th letter, which in this case is 300

This include limit inside your function, if for example a player types "-gold 30000000", the trigger will only read 30000000

If you don't want a limitation to your trigger, just change the final value to
Player - Add (Integer((Substring((Entered chat string), 7, (Length of (Entered chat string)))))) to Player 1 (Red) Current gold


This will give you a no-limit addition of gold to the player (but you will still have limit for hard-coded maximum gold per player in Warcraft III Game Engine)
