ordering a unit to flee

[Jooster]

is it possible through triggers to make a unit flee? would really help with my custom fear ability

 

[Samael88]

Add the peseant classification to the affected unit's when the ability is cast and have a dummy unit damage them for 1hp or something. That could work

 

[Sevion]

Get the angle between the unit and the caster. Add 180. Issue the unit to move to a point X distance away towards the angle we got earlier. It would look as though he's "running" away from the caster.

well so far what i got is

works decently well. any suggestions?

If you casted it more than once, it would get messed up. And sometimes, the unit would run towards the caster. Do as I said, and they'll run away always instead.

 

[Jooster]

well i don't really mind if the unit runs towards the caster. i was hoping for something along the lines of fear like in wow. but what do you suggest on doing to stop it from messing up if it were cast more then once

 

[Sevion]

If you did it in JASS you could easily use locals to fix the global overriding. :/

You could use Local-Globals. Just add:

Custom Script:    local location udg_point
Custom Script:    local rect udg_Temp_Rect
Custom Script:    local group udg_unit_group

Though, that's very frowned upon and if you're going to submit something, don't use them.

You could use arrays :/ Though, it's be really stupid to do so when you can use locals.

 

[Jooster]

could u explain the locals to me a little bit, i get the arrays but not quite so with the locals. and why would they be frowned upon?
