hey this is a jump spell from berb's projectile map.
is there any way of making this jump spell work for all players with only 1 trigger?
I got it to work but i had to make 12 seperate triggers since i dont know any jass

It alredy works for any amount of units and players, there's no need to create more. You just need to replace the "return GetSpellAbilityId()=='A0H9'" with the custom Id of your Jump ability.

so.. is player(0) supposed to be all players?
for some reason player(0) is actually player(1).

anyways figured it out.
just had to add

call TriggerRegisterPlayerUnitEvent(jump, Player(0), EVENT_PLAYER_UNIT_SPELL_EFFECT, null)

for players 0-11

turns out this was a stupid question hehe

Ooooooooh, see there:

call TriggerRegisterPlayerUnitEvent(jump, Player(0), EVENT_PLAYER_UNIT_SPELL_EFFECT, null)
// TriggerRegisterPlayerUnitEvent is the "A unit owned by player X" generic event.

1. Create a trigger
2. Add the event "A unit starts the effect of an ability"
3. Convert it to custom text
4. Look there for the trigger event, that should contain this "EVENT_PLAYER_UNIT_SPELL_EFFECT"
5. Replace the "call TriggerRegisterPlayerUnitEvent(jump, Player(0), EVENT_PLAYER_UNIT_SPELL_EFFECT, null)" with the jass equivalent of the "A unit starts the effect of an ability" which is the one we need.
6. Delete the other trigger, which was just to know how "A unit starts the effect of an ability" was written in JASS
