A fireball missile unit and ground target

[Herod]

Hi everyone, Im making a warlock of fire that casts fireballs
The fireball rules the missile projectile system (detonates when find unit or tree for ex)

I´ve not tried yet, I will do this today,

Would know if is possible, the fireball have two ways of target
1) ground - it explodes when reach the target point ground or unit or tree
and
2) Target Unit, in this case the fireball will chase the unit.

anyways was this TY to all!

You can base the fireball off Channel ability and set its 'Data - Target Type' field to 'Unit or Point Target'.
In trigger, when you cast the ability check if target unit of ability being cast == No Unit - if so, you have targeted a point.

Very good! Worked, any suggestion of special effects at the moment that the fireball explode?
Im using the projectile Red Dragon Missile, the explosion the Mortal Dwarf explosion, and Mark of death sound at moment of casting the fireball

Other thing, the fireball after X seconds expires and explode even without hit anyone

Need make one more thing here,
the fireball is working via Missile system. But has other issue, If the target is a unit, the fireball will search the enemy, but after X seconds the fireball must explode

Ive tried via countdown timer, but not working

I have Unit colision event, Tree colision event, and End event

• Timer Fireball
  • Events
    • Time - TimerFireball expires
  • Conditions
  • Actions
    • Set VariableSet Fireball_position = (Position of Missile__Dummy)
    • Unit - Create 1 Dwarf Dummy Fireball for Neutral Passive at Fireball_position facing Default building facing degrees
    • Unit - Add a 10.00 second Generic expiration timer to (Last created unit)
    • Unit - Order (Last created unit) to Attack Ground Fireball_position
    • Set VariableSet Missile__WantDestroy = True
    • Custom script: call RemoveLocation(udg_Fireball_position)

a single timer would break this if it needs to be MUI. Dynamic timers would be more usable, but is a more advanced topic, as you would basically have to have a timer pool where you keep your registered timers are recycle them (since you can add new timer event, but you cannot unregisters events).

If the missile system you use allows you to set trigger that should execute when the missile reaches the target, then you can easily just use timed life:

• On missile's creation, give it a timed life of X seconds
• Create a trigger that reacts to when the missile dies - do here whatever you want to do when fireball explodes mid-flight
• When the missile system detects that the fireball reached its target then turn off the previous point's trigger, then do whatever you do when fireball reaches the target, then kill the fireball and finally turn back on the previous point's trigger

Ok, but dont know how do this. This case, the fireball will explode, if the target unit evades the fireball, and the fireball will try to seek the target, but after a while it will explode
