Chaos Orc change?

How is the Chaos orc change done? In the mission where Grom drinks from the poisoned energy pool all his men nomatter where they are beco0mes an entire new model, with new stats and all! How is this detection & Changing process done...?

Lupus

Action : Unit Enters Region (BloodFountain)
Action : Pick every Grunt and replace picked unit with Chaos Grunt (repeat for all units)

Heh Heh theres unused ability in some fiiiles...also theres some chaos passive abilities.

Is there an automatic "pick every unit of a type command"? Because it has to work in a match where numbers of units are unknown?

What chaos abilities?

Lupus

Unit Group - Pick every unit in [units of type [whatever]] and do action

Everyone's answer to your question has lacked a bit of detail and information. To emphasis a bit, I'll get into more detail:

Events:
Unit enters region

Conditions:
none required

Actions:

(before i list the actions, take note that for EACH orcish unit that is available as chaos must each be given their own if/then/else function. I have listed 2 for you, if your using more... add more functions)

If (entering unit) equal to Peon, then do (replace (entering unit) with Chaos Peon with New unit's full life
If (entering unit) equal to Grunt, then do (replace (entering unit) with Chaos Grunt with New unit's full life


Depending on how you want these chaos orcs to appear will determine how the actions are executed. If you are still confused after reading my answer, please supply me with EXACTLY how you want your units to be turned to chaos and i'll help you out from there.

MrDoomMaster's trigger is good if you only want to replace units that enter the region. If you want it to do all units of whatever type in the map, then actions would be:

Unit group-Pick every unit in group (units owned by player (whatever) of type (whatever)) and do (replace with (whatever)...)

and copy that trigger for each unit type.

the hero thing with exp and stats is more complicated

I've never tried this, but I saw in the Battle.net forums a simillar discution and someone said there's an upgrade that, when researched, turns your army into chaos (i.e.: replaces all units and replaces also their training buttons, so that the Barracks, Bestiary, etc. will train now the chaos version). THis upgrade is not accessible to the player, but can be researched via triggers.

That's why Grunt, Grom, Peon, etc. have an "Chaos" ability (look at their stats).

However, since I never tried it, I don't know if this information is true. Look at the trigger that gives automatic research for this upgrade. If you don't find it, extract the orc map from the MPQ and look at its triggers. Maybe it uses custom text, who knows?

Well thx all i should be able to figure it out now..... :)
