[General] Triggered missile arrow

[Herod]

Im trying make archers and warrios to go inside a dungeon, but the archers has missile system colision and other stuffs. Idk what ability use for them fire triggered missile system.
I´ve tryed BlackArrow, but if I remove the damage, for them use only black arrow, even with autocast it doesnot fire, I need click on blackarrow and select an enemy unit. Any solution for this case?

You have many choices. You could have an instant-attack without projectile etc. that you set to 0 damage for the "instant attack" and "remove" the attack using DamageEngine (or natives, depending on your other triggers), then fire your projectile, without any ability involved. That's how I did Master Chief's weapons on my map.
You fire the missiles using triggers, right?

Otherwise you could use spell-based solution (any auto-castable spell on enemies set to do nothing), but that will make it harder to stuff that effects attack speed/damage to work.

Basically, it depends on your map, how you want it and what other factors you'd need to take into account.

what is instant-attack. My missile gui system fires with "A unit starts the effect of an ability". What it should be?? A unit is attacked?

 

[ThompZon]

What I mean by "instant attack" is "without projectile", on the unit, have "Combat - Attack 1 - Weapon Type: Instant".
Then use DamageEngine to detect when this unit-type attacks (checking unit type of damage source, attack-type (if the unit can cast spells) and that DamageEventType is 0, I.E. nothing is set, it is the regular attack), and when the projectile is about to deal damage, ensure that you set NextDamageType to something non-0 (1 for example).

Note that this will cause the damage to be "code" from the DamageEngine point of view. This might or might not effect other triggers using the damage engine.

what I must do now to enable colision with units and doodads? note: this projectile is not doing 200 damage as programed

jesus was messing with this thing and my archer shot like 1000 arrows and fireballs everywhere it almost crashed the computer

I´ve read the missile system thread and got it,

Now I need other issue, a destructible 1x1 that dont block vision of the buildings (doodads), to make "a collision with destructible"

 

[Uncle]

I imagine you want the Missile_Source to damage Missile_UnitHit rather than the Dummy unit. This way the Source unit that fired the missile gets the kill credit and triggers other damage events.

ok im not sure, when I get home I see this, But if it was the source unit instead dummy unit, the own arrow kills his own archer at the moment of the shot

The Dummy should belong to the same Player that owns the Archer so they can't possibly damage one another.

• Set VariableSet Missile__Source = DamageEventSource
• Set VariableSet Missile__Owner = (Owner of DamageEventSource)

^ Don't use (Triggering player) here.

This would be False:

• If - Conditions
  • (Missile__UnitHit belongs to an enemy of Missile__Owner.) Equal to True

  • (Missile__UnitHit belongs to an enemy of Missile__Owner.) Equal to True

But now other issue appears, the damage event event... it fires again again, to an infinite loop, making the archer shoots several arrows, ive done the missile cause the instant attack of the archer fires the trigger, but the missiledummy damage dont
maybe need trigger every archer in the map?

Note that the map has up to 30 archers
From what I've noticed, the damage that the dummy causes to the UnitHit is the same property of (damageEventType = 0) or normal attack

 

[Uncle]

You can turn off the damage engine before dealing damage to avoid causing the trigger to fire again:

• Trigger - Turn off Damage Whatever
• Unit - Cause damage
• Trigger - Turn on Damage Whatever

Remember that an Event will fire immediately after an Action happens. In most cases it happens on the next frame but sometimes it can even happen in the middle of a trigger like when a unit dies.

SOLVED TY TO ALL REPLIES

 

[Herod]

Almost solved, I wanna know how the arrow makes a perfect parabola over uneven terrain (red)
Actually it is making the orange trajectory if I order one archer attack other

 

[Uncle]

Does Chopinski's system not handle that already? Or are you using something else?

If the end position of the missile never changes then the formula shouldn't be too complicated.

@Uncle any solution???

 

[Uncle]

I don't know, you didn't answer my question and I didn't create the system. The system itself would need to account for ground height in addition to missile arc which isn't too complicated.

I imagine it changes from something like this:
SetHeight = missileZ

To this:
SetHeight = GetLocationZ(missilePoint) + missileZ
