How to make a unit bigger every second?

[Quetzalcotl]

I am wondering how I can make a unit get bigger every second, just like the EMP spell of invoker (in dota) but I can't figure out how

 

[M0RT]

There is an action in "Animation" cathegory called "Change unit size", I think it can do the job.

This is basicly what u need.

• GROW BABY GROW
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Blizzard
  • Actions
    • Animation - Change (Casting unit)'s size to (101.00%, 101.00%, 101.00%) of its original size
    • Wait 2.00 seconds
    • Animation - Change (Casting unit)'s size to (102.00%, 102.00%, 102.00%) of its original size
    • Wait 2.00 seconds
    • Animation - Change (Casting unit)'s size to (103.00%, 103.00%, 103.00%) of its original size
    • Wait 2.00 seconds
    • Animation - Change (Casting unit)'s size to (104.00%, 104.00%, 104.00%) of its original size
    • Wait 10.00 seconds
    • Animation - Change (Casting unit)'s size to (100.00%, 100.00%, 100.00%) of its original size

This is a realy basic trigger though, I gues it could be done in a better way but I don't know about it.
U can use this for starters and throw in special effects and I gues you need to store the unit into a variable to make it a good spell.

If you want to use Casting unit. Assign in to a variable and local it.

Until anyone has a better solution I'll stick to Airandius' technique, thanks dude!

 

[M0RT]

This is not a better solution, just corrected the one above:

• Enlarge Unit
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Blizzard
  • Actions
    • Custom Script: local unit tempUnit = GetSpellAbilityUnit()
    • Custom Script: local real scale
    • For each (Integer A) from 1 to 5
      • Loop - Actions
        • Custom Script: set scale = 100 + ( I2R ( GetForLoopIndexA() ) * 10 )
        • Custom Script: call SetUnitScalePercent( tempUnit, scale, scale, scale )
        • Wait 1.00 seconds

It works for one unit at time

 

[Airandius]

Whoa that kinda looks realy complicated, could you like explain it a bit?
What the custum scripts do?

Btw, I can edit my version a bit so it works for multiple heroes/ but only for one per player.
This is the version that has a variable.

• Grow Red
  • Events
    • Unit - A unit owned by Player 1 (Red) Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to Blizzard
  • Actions
    • Set PlayerRedHero = (Casting unit)
    • Animation - Change PlayerRedHero's size to (101.00%, 101.00%, 101.00%) of its original size
    • Wait 2.00 seconds
    • Animation - Change PlayerRedHero's size to (102.00%, 102.00%, 102.00%) of its original size
    • Wait 2.00 seconds
    • Animation - Change PlayerRedHero's size to (103.00%, 103.00%, 103.00%) of its original size
    • Wait 10.00 seconds
    • Animation - Change PlayerRedHero's size to (100.00%, 100.00%, 100.00%) of its original size

Now you have to make one of these for each player.
You can like assign the variable to the unit when it's trained aswell and do it with the second and thrid hero aswell, but that is only if you are planning to have more then 1 hero I gues.

The scripts create local variables for the casting unit, and the percentage size.
Then the cycle enlarges the unit five times, increasing the size a bit every time. "call SetUnitScalePercent()" is equivalent of "Animation - set unit size" and it's parameters are:
1. the casting unit, stored in local variable (tempUnit)
2.-4. unit new size (scale), calculated by the formula (100 + 10*A) (FOR cycle runs five times, each time increasing A by 1)

Your version would definitely work, too, but you have to write "Set unit size" and "wait" three times, which just isn't nice .

• grow
  • Events
    • Unit - A unit starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Your Ability
  • Actions
    • Custom script: local real udg_real
    • Set real = 100.00
    • For each (Integer A) from 1 to 5, do (Actions)
      • Loop - Actions
        • Set real = (real + 1.00)
        • Animation - Change (Triggering unit)'s size to (real%, real%, real%) of its original size
        • Wait 1.00 seconds

That's the way I would do it. I also tested it and it works. =)

You don't need a local variable for the unit since triggering unit always refers to the unit actually casting the spell.
Define a normal real variable (in this example called "real") first, then you just need one custom script line declaring the global variable to be local (udg_ is the prefix for global variables).
You can also replace the "from 1 to 5" to "from 1 to (Level of (Ability being cast) for (Triggering unit))" so it grows more depending on the level of the ability for the unit.

Note: If you cast your ability multiple times, the unit's size will always be set to it's original size and be increased again.

Ok, thanks for all the responds (and they are great) but is it also possible to cast a spell, create a dummy unit (like a ball or something) and make that one bigger every second?

 

[Triax]

No big difference, but you need a local unit variable.

• grow
  • Events
    • Unit - A unit starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Your Ability
  • Actions
    • Custom script: local real udg_real
    • Custom script: local unit udg_unit
    • Unit - Create 1 Dummy for (Owner of (Triggering unit)) at (Position of (Triggering unit)) facing Preset for building adjustment degrees
    • Set unit = (Last created unit)
    • Set real = 100.00
    • For each (Integer A) from 1 to 5, do (Actions)
      • Loop - Actions
        • Set real = (real + 1.00)
        • Animation - Change unit's size to (real%, real%, real%) of its original size
        • Wait 1.00 seconds

If you want to prevent memory leaks, you'll have to edit it a bit, but I think you can do this on your on. (use this tutorial or search via google)

When i first looked at it i thought; this is going to be it! So i made it, pressed the test button, used the spell and BOOM, fatal error >_>

 

[Triax]

Wow, that's kind of ... w000000t? I mean I just changed a few lines, so I didn't test that one too. Let's see ...

[edit] Obviously it's because of defining the local unit variable. I fixed it by using custom script, but don't ask me why this works ... Now you don't need a global unit variable. I also changed the additional size so you can see whether it works.

But I found out that the dummies grow sometimes more, sometimes less. Professional help is needed.
