Dummy Missiles

keychup

Active Member
I am using dummy units as missiles so that in case another unit fires a missile it will be possible to deflect it.

Now I have an ability which fires 16 missiles at once.

On my current method I add all missiles to a unit group the moment they are created then i move them along their corresponding paths.

All was smooth until I had to implement deflection in the trigger. The deflection actions take place within the trigger that moves the missile.

For this action, I pick all units in the missile group to find each missile and make them move, but in order to find their distance from other missiles i have to find each missile again within the initial "Pick every unit in Missile group".

So you understand that this is making my game jerky whenever two enemy missiles collide.

Suggestions?

EDIT: Who knows how I can hide the missile dummy's HP bar without adding locust? If I find out how I can do this i can check for a deflection condition with only nearby missiles instead of the entire group of missiles.

EDIT: Solved. Set unit's Circle Height to 2048.00 and circle size to 0.00

EDIT: A new problem rose. The dummy units' HP bars appear on the sides of my camera bounds sometimes.

EDIT: I may have solved it. Selection Scale was set to -10. No HP bars so far, and still possible to use the pick every units within range with missiles.

That actually made things worse. Perhaps it would be better if these missiles can be picked and damaged like a regular unit but i need to know how to completely hide the hp bar without adding locust.

If you add Locust to a unit, you will have to resort to picking every unit owned by the player and then checking if they're in range. I would go with adding Locust and just enumerating this way.

Afaik you can add locust to a unit, hide it, remove locust and unhide it again, so that locust will be gone while no player info / HP bar is shown. Read it somewhere, never tested it though since my projectile systems always failed over bridges :/

@BlackRose: we've already established that going through every unit wont work because that would increase the number of actions to be done exponentially. You can expect about 36 to 300 missiles to be on the screen at the same time. if i pick 300 missiles then go through each of those 300 missiles to check if they are enemy missiles, then i'd be causing the game to run 9000 times every 0.03 seconds.

@Imp Midna: I should try that.

Just tried it. Doesn't work.

It does work. This works:

Unit Group - Pick every unit in (Units of type Footman) and do (Actions)
Loop - Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
(Distance between (Position of Blood Mage 0013 <gen>) and (Position of (Picked unit))) Less than or equal to 600.00
Then - Actions
Game - Display to (All players) the text: footman
Else - Actions

But whatever works for you.

that does not solve the problem of lags: i still have to go through 300 units 300 times. and you are using a preset variable. there shouldn't be any preset units in the finished map. To pick every unit of one type won't solve the problem either. The challenge is to check all sorts of missiles within range. Your suggestion only worsens the problem. But so far I've been getting good results from setting circle size to -10.00 so thanks anyway.

That was merely an example to prove that enumerating in that fashion works. I assumed you had the same unit type for your missile, and that you simply attached the model as a special effect onto it. It simplifies things - having only one unit for all projectiles. This may be of some use to you. Although it might not since you're now content with your method. If so, you can probably disregard everything I've said so far.

You can change this now in User CP.
I'm not an expert on the editor, you should use the JASS script for this and it is a little complicated. But the pro's can help you with this.

I could give the general tip to not use the square root when you compare distances, but speaking about 90.000 runs that wont really help you though i guess. Also, the trigger would be stopped quite quick, i'd bet after number 10.000 so it will not even work.
Btw, why dont you just pick every missile around your missile in the given distance and deflect em? I belive the native pick every unit is faster then manually comparing em.

    I think leave it for real old news that cannot be sorted the reason we had it in the first place was a server issue that we do not have anymore. I don't want to get rid of the archive just not put anything in it for now until we figure it out more
