Wall bounce trigger

[Datnes]

I know it was here much times before.
But i need it pretty much to my map, so i asking again.
Does somebody know the equation of wall bounce, works for all angles?(in triggers)
(0 to 360)

 

[ikillforeyou]

?

I don't understand what you mean, maybe the ITT?

look in the spells section for ITT, it should help.

 

[Datnes]

I mean this function:

Like in pudge wars.

 

[ikillforeyou]

Let r be the angle of the ray, and R the angle of reflection.

If the wall is flat (i.e., if its angle is 0), then we know that r + R = Pi/2.

Now suppose the wall has angle w. Then rotate the diagram by -w,
so that the wall is now flat again, and the angles of the ray and its
reflection are now r - w and R - w, respectively.

We then have (r - w) + (R - w) = Pi/2, which should give you enough
information to find R.

This is not a formula for w3 triggering.
I want just something usable in triggering.

It is clear to (180 - Angle) works only for vertical sites.
But i need formula for Horizontal sites.

 

[sephiroth1234]

Maybe RADIAN(3.14159 x ANGLE) function will work in.

Yea but it works only for vertical sites.

How about using jass?^^ alot easier with the formula he gave you, put it in a library, make it public... and ta-daa..

Thanks!
It really works! +REP

Here is the trigger:

• Set TempReal = 0.00
• Set TempReal2 = 0.00
• For each (Integer B) from 0 to 3, do (Actions)
  • Loop - Actions
    • Set TempReal = ((Real((Integer B))) x 90.00)
    • Set TempPoint = (Position of TempUnit)
    • Set TempPoint2 = (TempPoint offset by 25.00 towards TempReal degrees)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Terrain type at TempPoint2) Equal to Lordaeron Summer - Dark Grass
      • Then - Actions
        • Set TempReal = ((Real((Integer B))) x 90.00)
        • Set TempReal2 = (Facing of TempUnit)
        • Set TempReal2 = ((TempReal2 + 180.00) + (2.00 x (TempReal - TempReal2)))
      • Else - Actions
    • Custom script: call RemoveLocation(udg_TempPoint)
    • Custom script: call RemoveLocation(udg_TempPoint2)

Can someone please explain to me what is a JASS or a GUI? Sorry i'm new

GUI - game user inteface. This is what you look at in normal editor in tirggers editor.
Jass in language used in war3 to perform any types of trigger action.
Whenever you create a normal trigger in GUI you can simply convert it to your own text via menu in Trigger Editor and text you gonna see is Jass.

GUI is easy to opperate with, although Jass ofers many new options and if you understand it well its quicker and cleaner.

 

[dardas]

And suprisingly, it's alot easier to work with if you know (Edited from: Need) c++, visual basic, c#, html, java codes, or so on. that gives you a full overview..

and that reminds me, can any 1 translate the bounce trigger to jass for me?
i wanna learn how to use that in jass. thanks in advance =]

it does spark a small light at the end of the tunnel, but it's rather dim... maybe an example would solve my problem? if you please.

GUI is Graphical User Interface and JASS, or JASS2 as Blizzard called it, is a scripting language.

Example of GUI:

• Unit - Kill Unit (Triggering Unit)

Example of JASS

call KillUnit(GetTriggerUnit())

so basiclly GUI and Jass are two ways to create triggers? I know and understand GUI but i've never seen jass before

 

[dardas]

gui is made out of jass behind the scenes.
gui is more arranged, and easier,
while jass can be messy with the wrong person.

and also, jass is alot better, for the basic idea it can use coordinates/more functions, and etc..
while gui has its limits.

function Trig_Example_Trigger_Func003Func004C takes nothing returns boolean
    if ( not ( GetTerrainTypeBJ(udg_TempPoint2) == 'Lgrd' ) ) then
        return false
    endif
    return true
endfunction

function Trig_Example_Trigger_Actions takes nothing returns nothing
    set udg_TempReal = 0.00
    set udg_TempReal2 = 0.00
    set bj_forLoopBIndex = 0
    set bj_forLoopBIndexEnd = 3
    loop
        exitwhen bj_forLoopBIndex > bj_forLoopBIndexEnd
        set udg_TempReal = ( I2R(GetForLoopIndexB()) * 90.00 )
        set udg_TempPoint = GetUnitLoc(udg_TempUnit)
        set udg_TempPoint2 = PolarProjectionBJ(udg_TempPoint, 25.00, udg_TempReal)
        if ( Trig_Example_Trigger_Func003Func004C() ) then
            set udg_TempReal = ( I2R(GetForLoopIndexB()) * 90.00 )
            set udg_TempReal2 = GetUnitFacing(udg_TempUnit)
            set udg_TempReal2 = ( ( udg_TempReal2 + 180.00 ) + ( 2.00 * ( udg_TempReal - udg_TempReal2 ) ) )
        else
        endif
        set bj_forLoopBIndex = bj_forLoopBIndex + 1
    endloop
    call RemoveLocation(udg_TempPoint)
    call RemoveLocation(udg_TempPoint2)
endfunction

//===========================================================================
function InitTrig_Example_Trigger takes nothing returns nothing
    set gg_trg_Example_Trigger = CreateTrigger(  )
    call TriggerAddAction( gg_trg_Example_Trigger, function Trig_Example_Trigger_Actions )
endfunction

I manually created the GUI and converted it. I think these are his vars but I can't be 100% sure.

 

[dardas]

way too much bj's, variables that has no reason, etc..
i've found a easier way in another forum anyways, so thanks anyways =]
