[Trigger] Presets for ordering units

[ryanshowseason2]

Is there any alternative for ordering units to use an ability than the presets? or is it possible to add more to the presets or change them? I want to order a unit to use a custom ability under certain circumstances. There are many instances of this ability so simply changing the base ability wouldn't be effective.

So is there a way around this? A quick fix, or pointing me in the direction of a good tutorial would be greatly appreciated.

Thanks as always, this forum is very helpful to me always.

You can force UI keys, but the simplest way is too just not base things off the same ability. Also you can create dummy units, and order them to cast the spell.

Also, have some reputation for being reasonable, and kind.

I'm basing the abilities off of charm which is the only spell I know of that changes a units team. Besides possesion, but that changes the color of the unit then as well kills the casting unit which makes things a bit more complicated, requiring the use of a summoning ability then instantly ordering the unit to use possesion... Much more complicated than just using a replication of charm.

But how do you order a unit to cast an ability besides the presets? or is it just not possible?

The ui keys though... Are those in essence like the memory locations the spells? And I could just change them around so the trigger thinks its ordering one ability but really doing another?

Force UI keys, just completes the action as if the player had pressed said key.

Order presets are just order strings, which cannot be added and I think that presets contain all strings.

Neutral Dark Ranger - Charm (for example), just represents the Order String - Use/Turn On "charm" field. Thus, you can in reality cast any ability whose Order String - User/Turn On is equal to a common racial/neutral ability.

In Jass, however, you have complete freedom, for example call IssueTargetOrder(c,"charm",u), so for certain cases in which you can't do the order in GUI (for example cancel), you can use the Jass versions (Note: in the case of cancel you actually need to use an OrderId with call IssueTargetOrderById(unit,orderid,target)).

Correct me if I completely miss the point here, but don't you want a unit to be able to use a ability, and only use that ability at a certain moment/event?

In that case, it's pretty simple. You create the unit in the Object Editor, or edit a existing unit. Add the ability you made to "Abilities - Normal".
If you want the ability to activate at a certain moment/event, you'll have to make a trigger for that. The trigger will cause the unit to activate the ability when something happens, like: the units life is lower then X life, the units mana is higher then X mana, the target of the unit loses a buff, or something else depending on the trigger.

If that is what you're looking for, just tell us what should happen to let the unit activate the ability, and we can help you create a trigger for it.

Alright this helps very much. In essence I could already use the abilities with the charm activate. *smacks self on head*. Thanks for the help though everyone.

That Jass is especially interesting as well purplepoot.
