[JASS] Local Tree Fade

[TheBlooddancer]

Will anybody be able to create a Tree Fade system, that changes the Opacity of 'Trees' in

900 range, to 90.
800 range, to 80.
700 range, to 70.
600 range, to 60.
500 range, to 50.
400 range, to 40.
300 range, to 30.
200 range, to 20.
100 range, to 10.

Use a custom model (Not trees!, but Units with the models!).

This would be really neat, and surely usefull for more than me.

(Must be Local, so that it only changes to the owner of the unit in range.)

Ps. Mustn't leak.

Okay, consider it done :]

Ok

You're trying to do this for every unit in the map or only an array of heroes or something? It will lag like hell for all the units.

Its not that easy, as there are no natives to set destructable transparency. Also animations bug as even if you slow them down, they resume their normal stand animation after the normal un modified time.

Only for the 'hero' unit.

Or actually, the selected unit.

Its not Tree's. Its units, with a tree model.

Oh finally someone made it clear they are units and not doodads or destructables.

Yea i did. In first post- now.

There are certain natives to avoid that.

Anyways, here is the code.

library FDT

globals
    private constant integer treeId = 101 //Use your dummy unittree point value id.
    private constant real fadeRange = 1000. //The fade range.
    //---
    private group tempEnum = CreateGroup()
endglobals

private function IsDummyTree takes nothing returns boolean
    return GetUnitPointValue(GetFilterUnit()) == treeId
endfunction

function SetTreeTransparency takes unit fromWho returns nothing
    local unit u
    local real x0 = GetUnitX(fromWho)
    local real y0 = GetUnitY(fromWho)
    local real dx
    local real dy
    call GroupEnumUnitsInRange(tempEnum, x0, y0, fadeRange+100, Filter(function IsDummyTree))
    loop
        set u = FirstOfGroup(tempEnum)
        exitwhen u == null
        call GroupRemoveUnit(tempEnum, u)
        set dx = GetUnitX(u)-x0
        set dx = dx*dx
        set dy = GetUnitY(u)-y0
        set dy = dy*dy
        if GetLocalPlayer() == GetOwningPlayer(fromWho) then
            call SetUnitVertexColor(u, 255, 255, 255, R2I(SquareRoot(dx+dy)/1000*255))
        endif
    endloop
endfunction

endlibrary

And here is a testmap...
