Detect and Count Unit Movement

[Radicool]

So as the title says. How can I detect and count a unit's movement? I think the best data to
collect is the distance the unit has moved. The number of move orders isn't going to work.

Also, I need to know how to create an event from this. For example, once the unit has moved a
random distance between X and Y, actions will occur. Then I can reset the movement counter.
Is this possible at all and in GUI?

You can go to the Spell Catalog and search for Bribe's Damage Engine. It has a function to detect whether a unit is moving or not.

Through further research, I have found this thread:

http://www.hiveworkshop.com/forums/triggers-scripts-269/how-make-distance-storing-not-leak-233477/

I can count the distance now.

• Game - WalkAmount becomes Greater than or equal to (Random real number between 1000.00 and 2000.00)

I use this event to detect how far I have travelled. "WalksAmount" being the variable used to store my distance.

I have two problems though:

1.) My "Walk Amount" distance always starts at 1240.
2.) The event always seems to trigger at about 1930. I DO NOT have "Fixed Random Seed" checked within preferences.

Any help please?

show triggers...

Ok. Fixed the first problem by setting WalkPoint2 at map initialization. Now, the Walkamount correctly starts at 0. But, the trigger still seems to fire at 1930. Its not random for some reason. Here are my Triggers:

• Map Initialization
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Set WalkPoint2 = (Position of Footman 0002 <gen>)

• Count Distance
  • Events
    • Time - Every 0.10 seconds of game time
  • Conditions
  • Actions
    • Set WalkPoint1 = WalkPoint2
    • Set WalkPoint2 = (Position of Footman 0002 <gen>)
    • Set WalkAmount = (WalkAmount + (Distance between WalkPoint1 and WalkPoint2))
    • Custom script: call RemoveLocation (udg_WalkPoint1)
    • Custom script: set udg_WalkPoint1=null
    • Game - Display to (All players) for 2.00 seconds the text: (String(WalkAmount))

• Encounter
  • Events
    • Game - WalkAmount becomes Greater than or equal to (Random real number between 1000.00 and 2000.00)
  • Conditions
  • Actions
    • Game - Display to (All players) for 5.00 seconds the text: Enemy!
    • Game - Display to (All players) for 5.00 seconds the text: (String(WalkAmount))
    • Set WalkAmount = 0.00

The Text messages are for testing purposes only.

Edit: It seems each time I test the map, the trigger fires at different WalkAmount numbers. Its as if its randomly picked for that game, and your stuck with that random number for the whole game. It does not generate a new number each time it triggers, but rather each time you play the game.

the reason it fires at 1930 is because the random real event gets created once at map init. It does not get a random number every time it is fired.

 

[Imp Midna]

native TriggerRegisterVariableEvent takes trigger whichTrigger, string varName, limitop opcode, real limitval returns event

You bind a variable by the name of varName to the real by the name of limitval. You expected it to bind the variable to the function (random value between x and y), when in fact you bind your variable to the real resulting from this function, causing the threshold to be set once at map initialization. While the real resulting from the function varies between the games, the threshold will not change once the trigger was created, resulting in your observations.

imp said it in a more detailed way.

@radicool
if u want it to be random use an ITE in the actions. in the event use greater than 1000 or something like that.

How can I get a new number every time it is fired?

if u want it to be random use an ITE in the actions. in the event use greater than 1000 or something like that.

• Encounter
  • Events
    • Time - Every 0.10 seconds of game time
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • WalkAmount Greater than or equal to (Random real number between 1000.00 and 2000.00)
      • Then - Actions
        • Game - Display to (All players) for 5.00 seconds the text: Enemy!
        • Game - Display to (All players) for 5.00 seconds the text: (String(WalkAmount))
        • Set WalkAmount = 0.00
      • Else - Actions

You going to need to elaborate. This didn't work for me either. I don't understand Imp's explanation, so I'm not really sure what the problem is here.

 

[pOke]

I haven't read the whole thread fully, but to get a random real

• Set TempReal = (Random real number between 0.00 and 2000.00)

Its under "Math- Random Number"

 

[deathismyfriend]

Use this as the event.

• Game - WalkAmount becomes Greater than or equal to 1000.00

You should also set the random value to a value then change the value in the then block of the ITE to a new random value.

Read the thread before posting....


Edit:

Something like this should work

• Encounter
  • Events
    • Game - WalkAmount becomes Greater than or equal to 1000.00
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • WalkAmount Greater than or equal to WalkRandomReal
      • Then - Actions
        • Game - Display to (All players) for 5.00 seconds the text: Enemy!
        • Game - Display to (All players) for 5.00 seconds the text: (String(WalkAmount))
        • Set WalkAmount = 0.00
        • Set WalkRandomReal = (Random real number between 1000.00 and 2000.00)
      • Else - Actions

After every time it fires you could destroy and recreate the trigger. This lets you attach a new event to it and gets rid of the old one.

I am pretty sure it would be easier to check the value yourself every time you update it. This way you can use a variable to represent the amount needed and that can be updated every time the limit is reached.

That is also true he can move this whole ITE in my above post into the trigger that sets the movement distance.

Ahh, this works perfectly. Thank you very much. I now have a working movement system

Glad it is working now.
