So, what I want is a unit to be able to fire while moving, and for that missile to head in a straight direction towards that unit, but not home into the target, and if it misses, it does 0 damage. It'd also be nice to make it be able to hit other, untargeted units if it touches them before the targeted unit. Any ideas?

Oh, and I already have the fire while moving thing, it's just the non-homing part I need.

So like a Yamato Cannon ability that can be fired while moving and targets an area rather than a unit, hitting everything in it's path?

Attack is a targetable ability, it will only take a target unit. What you need to do is fairly complicated. You would probably need a behaviour with a periodic ability that searches for enemies around the unit and then fires to the point where an enemy is found.

Then you can have a behaviour on the missile that is launched that searches a very tiny radius around it for enemies then does damage to the enemy and kills it self when it finds one.

Here's a crude example of what I have in mind:




Making it hit someone in-line isn't 100% needed, just something that would help. But how would I make the missile capable of being dodged and non-homing?

You can use dummy units and triggering to get it done, but it's probably easier to do with data edits. Which I'm not good with.

So based on that diagram, is there a range for the ability, or does it just shoot until it hits something?

As y'all've prob'ly figured out, I'm not too familiar with SCII, but I know that units can launch other units as an attack...

Perhaps you could make the missile an air unit. Give it its own attack with a very short range, and make that attack a suicide attack (damages what it hits, and kills itself).

What he's asking is easy enough to do with a regular missile attack, too.

There should be a range for the ability. Also, (again, not 100% necessary) I'd like it to impact against walls.

EDIT: Found out the dodging can be handled with movers. But it's really flawed for what I want. If the unit moves even a pixel out of place after you fire the weapon, it will completely miss. I didn't do too much experimenting, it was mostly duplicating the Virophage's weapon and making it used by the Photon Cannon. If someone wants to have a go at it, please feel free. I'll be working on other stuff for now. But I will need this to be accomplished, or the map will be incredibly difficult to make.

Go and download my Shooter Map for a perfect example of what you want.

Modifications would include changing the Events to something like "A Unit is Attacked," and then changing the create unit position parameter to that of the Attacking Unit. Furthermore, the Actor for the Bullet units would have to be changed. Overall, a few quick changes and simplifications of my existing system will get you on your way.

The key aspect is creating a unit that kills itself when it gets in a certain range of an enemy unit. The unit itself would have a behaviour that causes it to deal damage on death.
Thus, whenever it comes in range of an enemy, it "explodes."

Change the target of the Launch Missile effect to Target Point. For the splash damage while in transit, create a Search Area effect that damages nearby enemies, create a behavior that calls it periodically, and give that behavior to the missile. No need for triggers.

I believe he wants it to self-destruct upon impact with anything while in transit; I assume that the Search Area effect would not cause the missile to self-destruct.

It could, the search can cause whatever sets of effects you want.

But the question is, how would I make the missile be destroyed when hitting an enemy?

The effect set has to have the following effects in that order: damage effect, suicide.
The effect set is executed by the search effect.

That was the first thing I made for my D1 map (a working fireball that is getting removed after a period of time) and deals damage on touch.

So, in the Areas field, I should add 'Suicide' after the damage effect?

1. searchEffect that calls an effectSet in the search area field
2. effectSet contains the following effects: damageEffect, suicide (suicide already exists)
3. damageEffect is a normal damage effect

I've used the campaign's unit "terror" as reference for attack + suicide.

But I used a unit and not a projectile (because I don't know how to shot projectiles with triggers and projectiles are only a special class of units).

If you still have problems, I can post an example map.

You can give a projectile behaviors, just like normal units... Use a behavior to call the search effect periodically (and frequently).

Has a bunch of projectiles with behaviors

EDIT: @ahli: Use one of the Create Effect trigger actions to fire a projectile from a unit via trigger. They're under Environment for some reason. Which is kind of dumb... We can't be polluting the environment with trigger actions like that!

Very well aware of that.

I'll try your method Ahli, I'll report back when I implement it.
