[Spell] fireball spell

[Kartron]

how do i make a fireball spell that explode on enemy contact? something like fireball in the map 'warlock'

 

[Malhorne]

You want a missile that go to the unit and explode creating a schockwave at the collision ?
If yes go request a spell in Mister Bean Spell Workshop

 

[pOke]

I'm sure you can also consult the spell section as something in there is surely modifiable to what you're asking for, otherwise it would be easy to make yourself too .

 

[Golden-Drake]

i hope your spell is based on trigger
if it is you can just make a unit group that contains all enemy units within a range of the fireball and if the ammount of units in the group is higher than 0 it has struck an enemy.

Quite simple

 

[Malhorne]

But if you want the fireball to move by trigger and you want this MUI it will be a bit harder

 

[Rheiko]

firstly, is this an AoE or single target spell?
if single, make a Fire Ball ability based on Fire Bolt, change the missile to fireball then use DDS, create an explosion special effect at that unit
if AoE, do as Golden-Drake said

@Malhorne
you can just use DDS and based the ability on firebolt with missile changed if it is Single Target
but if it is an AoE spell, yes. the fireball's movement must be triggered

Check the Homing Missile thing in my signature.

 

[FUJI]

Make a missile to the position of caster, add the missile to the group and loop it to the group which is moving, save the important datas in the hashtable, make spell stage 2, Pick every units in the missile ( random unit in the group ), If it is true then kill the missile or remove, add the picked units in the group and save again the important datas about knockback, make the spell stage to 2, after that check if the spell stage is 1, knockback the unit to the angle of their position, Duration or Distance must be reached before removing the knockbacked unit and Flushing child the ID or Keys to the hashtable, Decrease the spell instances, Check ITE if instances == 0 then turn off. Well Done!

 

[Losam]

To build this you need spell check (via locations) if any unit / osbtaculo that meets your need. So when the fireball move and find some obstacle, it will explode.

[Rheiko]

i hope this is what you want

@jakeZinc
If my guess was right, what does he mean is already inside the test map (the single target)

[Vinz]

Rheiko, you should put prefixes in the variable names as they might collide with other things.

 

[Rheiko]

They didn't collide though
I try it
if you want change it just change it, i'm lazy =P
