How to make spells instant?

Well , i want to know if an instant type spell like thunder clap can be made into a selecteble one like shadow strike....

what makes an ability instant or selectable, is this something that can be found in object editor or must i use trigger to change this aspect of the spell


as an example, i want to make the ability thunder clap selectable and that it only damages one target , the one selected, instead of everyone around the hero....thx ^_^

nope. Not by changing one field.

The only spell capable of that is the spell "channel". Channel is made for us to trigger some spells.

If you want to do, for example, a thunder clap at a location. You'll need to make a new spell, based on one that has a target location. Then make a dummy unit cast thunder clap at a target location. gl

thx for the info, but i have another question,

how about making a thunder clap spell that only damages one unit infront of the hero caster....is that possible....the spell would be like the original, instant, but how can i make it target one unit , the unit infront of the hero...

set damage to 0 and duration to 0.01. Then when a unit casts the spell, take the unit in front of him (u can take him by unit group and checking angles) then use the unit - damage action.

im having a little trouble with the triggers, could u help me with that plz ^_^

Why don't you just use the spell shadow strike, since its slows the target, is selectable, and only affects 1 unit. Just change the damage per second to 0 and the buff similar to thunderclap.

that would be good, but i just found the attack system perfectly the way i wanted it.. the only thing is its in jass ....and i dont understand jass at all

has anyone ever played azeroth grand prix( the racing map made by blizzard) well one of the abilities is the machine gun ability, but its instant, as soon as u press the hot key it shoots....this is perfect....but i dont even know where to biggin to import it , i dont understand it ...


if anyone can help me , i would like to know if that can be done with triggers, because then all i would have to do is the triggers and reduce the range(i think).... ^_^
