Detecting artillery style aoe and source

[xD.Dunedain]

Hi,

I have a rain of arrows spell which uses artillery units to attack ground at location, spell works fine but i recently added a custom damage system as well and now i need to detect when a unit is hit by the artillery.

-EVENT_PLAYER_UNIT_ATTACKED does not detect artillery attacks
-knowing the location of the attack does not help me because of flight time, i know how to make arrow functions using timers but i don't want to because i want the arrows to have very high arcs and i dont know how to make arrows look correctly during the arc
-EVENT_UNIT_DAMAGED can detect artillery attacks and GetEventDamageSource() will show me what caused the damage but i will have to add almost every unit to the trigger

so my question is it ok to add every unit as they enter the map to the trigger or is there another solution or am i boned?

Thanks

Use a damage detection system, it will add all the units in the map to the damage event.

Then you use the damage system's event to in your trigger, and check the unit type of the damage source.

Thanks for the reply ruler,
i'm currently using a simple damage detection system i found on thehelper by emjlr3, that i can easily understand, manipulate for my purposes and has worked fine for me up until now.
I've done a stress test with the EVENT_UNIT_DAMAGED trigger on every unit with 500 units added and removed to the map in lots of 50. i didn't notice any increase in lag, so i'm going to assume it's okay to use, unless an expert says its got some hidden devilry in it.

It sounds like you know what you're doing

Did you use Windows Resource Monitor to check if there is a constant increase in memory usage?
