DotA - Powershot

[tml616]

Can anyone post a link to the code for the Powershot spell from DotA's Windrunner, or any other triggered line damage spell?

Create a dummy unit and move it with acceleration? And for the damage part have like a real like 1.0 at the start and for every hit it does reduce it 0.1 (this makes it deal 10% less dmg each hit). Quite a basic projectile spell

That's why I want the code

Tried too make this one in GUI but havnt used GUI in like 2 years now, so it was very confusing ^^ You have so bad over view of the triggers. JASS ftw! (Could make you a VJass script in a sec if you'd like)

EDIT: Made a basic projectile spell for you, so you can see how you make the movement and stuff

        • -------- Load the stuff we save the the hash (or well the unit atleast) --------
        • Set TempUnit = (Load 1 of (Key (Picked unit)) in PowerShot_Hashtable)
        • Set TempLoc = (Position of TempUnit)
        • -------- You can see i load the angle in this line below (Reals cant leak and i only need to load it once) --------
        • Set TempLoc2 = (TempLoc offset by 10.00 towards (Load 0 of (Key (Picked unit)) from PowerShot_Hashtable) degrees)
        • -------- Move the dummy --------
        • Unit - Move TempUnit instantly to TempLoc2
        • -------- Below here you prolly want some thing that stops the spell eg. when it move X distance or something --------

These 2 last triggers leaks as hell, but well we can get everything here in life

I already know exactly how to code the spell to do damage in a line, but it is impossible to make MUI.

All I need is how they make the spell MUI.

My problem is with my spell Infernal Wave, it causes damage in a line.

I make it pick all enemy units in 200 range of the projectile and do the following:
Deal damage
Add unit to "was hit" unit group

I can't have it MUI if the "was hit" group is a global variable (I am not going to make an 8192 array for it). But there is no way I can see, even with hashtables, to make it MUI. Since the hashtable unit group handle must refer to a global unit group.

For now, I have it MPI with "was hit [number of triggering player]" but this is still half-assed and it must be MUI if at all possible.

 

[Ciebron]

Do able with a local group

And yeah a group array and have a index for the spell and it should be no problem

 

[tml616]

can you use local groups in periodic triggers?

 

[Ciebron]

yeah and pass them in a hash table

 

[Adiktuz]

I think you dont need local groups really, just save the group in a hashtable and evrything will be okay(considering you know how to work with hashtables)...

 

[Ciebron]

Yeah but if have 1 group for lets save 5 instances of the spell it wont be really MUI :/

right now the periodic unit group pic is the biggest performance eater so you should look out for some JASS dude who'll make you a function or something which damages units in an aoe around x/y-coordinates, adds them to a unit group and creates a special effect

the other stuff should be perfect (I hope)
at least you can spam it a few times without breaking the game

edit:
made damage adjustable
