How can i see when a spell hits a player

[CrashKurs]

Hi
i want to make a spell like WoW's spell Lava eruption from shaman, with a floating text about it which shows the damage of the spell(random between 2000 and 2500)
but how can i detect when the spell missile hits the target ? is there any function ? or something like (Distance between point of caster and target / missile speed )
hope for a fast request

(Real) Math - Distance Between Points
Make sure you add the Points to variables and Remove the Points after that so it doesn't leak.

y but how can i know the time the missile needs to fly until it hits the target ?
i want something like a function with distance between points and the missile speed

You have the distance, you have the missile speed, make tests. I would start from here: Time = Distance / Missile Speed. If it doesn't work correct, then add/substract time until you find the correct form.

You can always use a dummy, thats is ordered to attack the target unit, instead of testing with distance/missle speed.

Also, you can use custom value to determine level of ability and therefor determine the amount of damage and effects that will occur when the spell hits the target.
