Projectile Offset Problem.

[Steel_Stallion]

well i tried alot of things on this problem, but i cant figure out how to do it.
so basicly im making a projectile system where as, 3 cannon balls fire from either side of the ship.
I just need to figure out how to make them fire from the left/right side, and the other one will be easy to figure out.
so i thought i would edit/use Mini-me's projectile system code (thanks alot mini-me[I think he's the chieften of clan cbs]) , and modify it. So i did.

This is what i have so far:

• Cannon Ball
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Fire! (Neutral Hostile)
  • Actions
    • Set TempPoint1 = (Position of Human Battleship 0000 <gen>)
    • Set angle = ((Facing of Human Battleship 0000 <gen>) + 90.00)
    • Unit - Create 1 Cannon Ball for (Owner of (Triggering unit)) at TempPoint1 facing angle degrees
    • Custom script: call LaunchProjectile(bj_lastCreatedUnit, udg_angle, 10.00, 800.00, 3.60, true)
    • Unit - Create 1 Cannon Ball for (Owner of (Casting unit)) at ((Position of (Last created unit)) offset by (0.00, 80.00)) facing angle degrees
    • Custom script: call LaunchProjectile(bj_lastCreatedUnit, udg_angle, 10.00, 800.00, 3.60, true)
    • Unit - Create 1 Cannon Ball for (Owner of (Casting unit)) at ((Position of (Last created unit)) offset by (0.00, 80.00)) facing angle degrees
    • Custom script: call LaunchProjectile(bj_lastCreatedUnit, udg_angle, 10.00, 800.00, 3.60, true)
    • Custom script: call RemoveLocation(udg_TempPoint1)

this script works perfectly, except when the ship faces horisontally.
see when it faces vertically, it works like a charm, firing on the right cannon bow of the ship.




see it works yay!

but when it faces the other waayyy...





The balls dont fire right....

any help is appreciated guys, ill attach the map too if you wanna take a look.

oh also for another related problem i think

now udg_temppoint1 is a Temppoint 1 named variable. What if it was an array:

Temppoint 1 [Player number of (owner of (casting unit))]

whats the jass thing for that? sorry i hate jass and i dont know much about it

1. You're leaking 2 point locations every time you fire.
2. The problem is that you always create your units aligned vertically. Instead, create them depending on the angle your ship is facing.

EDIT: fixed your trigger.

• Cannon Ball
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Fire! (Neutral Hostile)
  • Actions
    • Set angle = (Facing of (Triggering unit))
    • Set TempPoint1 = (Position of Human Battleship 0000 <gen>)
    • Set TempPoint2 = (TempPoint1 offset by 80.00 towards angle degrees)
    • Set TempPoint3 = (TempPoint1 offset by -80.00 towards angle degrees)
    • Set angle = (angle + 90.00)
    • Unit - Create 1 Cannon Ball for (Owner of (Triggering unit)) at TempPoint1 facing angle degrees
    • Custom script: call LaunchProjectile(bj_lastCreatedUnit, udg_angle, 10.00, 800.00, 3.60, true)
    • Unit - Create 1 Cannon Ball for (Owner of (Triggering unit)) at TempPoint2 facing angle degrees
    • Custom script: call LaunchProjectile(bj_lastCreatedUnit, udg_angle, 10.00, 800.00, 3.60, true)
    • Unit - Create 1 Cannon Ball for (Owner of (Triggering unit)) at TempPoint3 facing angle degrees
    • Custom script: call LaunchProjectile(bj_lastCreatedUnit, udg_angle, 10.00, 800.00, 3.60, true)
    • Custom script: call RemoveLocation(udg_TempPoint1)
    • Custom script: call RemoveLocation(udg_TempPoint2)
    • Custom script: call RemoveLocation(udg_TempPoint3)

Oh yeah, and try basing your ability off "Channel". Otherwise you'll have to find a good ability for your "left" attack.

Well, i did it, it DOES work, perfectly infact, except that now, for some reason, it lags like hell when i fire.

I did everything right, and it didnt lag before... whats the cause?

 

[busterkomo]

leaks? Or maybe the slow GUI unit creation..

 

[Eleandor]

lag??

I tested it in my map, no lag at all.
Please attach your map again...

 

[Steel_Stallion]

oh wait, nvm... works fine now, that was weird.

Thanks! +REP

Btw, you know how its callremove(udg_Temppoint1)

What if Temppoint 1 was an array where

Temppoint 1 [Player number of [Owner of (Casting Unit)]]]
whats the script for that?

 

[Eleandor]

it's something like call RemoveLocation(udg_TempPoint[getPlayerID(getcastingunit())]) but I don't know it exactly. Check the JASS syntax somewhere?

Anyway, you don't need that in triggers without waits as they usually are MUI already.

Alright thanks, my problems be solved! (if only i can rep you twice)
