Flashlight Effect?

[Shadowz123]

Is it possible to create a Flashlight effect using only triggers and not JASS?

 

[mikke95]

What do you exactly mean by FlashLight Effect..?

 

[Squishy-1]

yeah i dont know what flashlight is but i assume u could do
event=
condition=
action= create special effect flashlight at "000 gen"

 

[Shadowz123]

Flashlight...as in a torch...so u could make a certain distance to see with an affect of a torch...as in a radius of the torch.

 

[Squishy-1]

you could create a aura of light with the radius from the doodad

Couldn't you create a region that had a visibility modifier?

If, say, every 0.5 seconds of the game, you made the map invisible, then created a region around the player and set the region visible. At the next time interval, destroy the previous region and repeat the same process again. I haven't tried this so I don't know if it will work, but it's an idea nonetheless.

If it's for an online game, don't you think such a trigger would cause a lag, Pirho?

And another problem would be that you cant destroy visibility modifiers.

 

[Squishy-1]

you can kill them or replace them with nothing through gui

It might. I have not tried it out yet.

0.5 is laggy even 3 is laggy

Ok, I just tried things out with a circular visibility modifier (every 0.5 seconds) and I encountered no lag. However, I think it would be more efficient just using the unit's sight radius against the fog-of-war to simulate a circle of light. It would certainly be more efficient if you could get away with it.

My test map simply created a footy in the middle of the map that you can move around. The sight range modifier followed him around.
Test code, for reference:
[jass]
function Trig_init_Actions takes nothing returns nothing
local location p1 = GetRectCenter(GetPlayableMapRect())
local location p2
call CreateNUnitsAtLoc( 1, 'hfoo', Player(0), p1, bj_UNIT_FACING )
set udg_footy = GetLastCreatedUnit()
set p2 = GetUnitLoc(udg_footy)
set udg_vmod = CreateFogModifierRadiusLocBJ( true, Player(0), FOG_OF_WAR_VISIBLE, p2, 2000.00 )

call RemoveLocation(p1)
set p1 = null
call RemoveLocation(p2)
set p2 = null
endfunction

//===========================================================================
function InitTrig_init takes nothing returns nothing
set gg_trg_init = CreateTrigger( )
call TriggerAddAction( gg_trg_init, function Trig_init_Actions )
endfunction
[/jass]
[jass]
function Trig_test_Actions takes nothing returns nothing
local location p = GetUnitLoc(udg_footy)
call DestroyFogModifier( udg_vmod )
set udg_vmod = CreateFogModifierRadiusLocBJ( true, Player(0), FOG_OF_WAR_VISIBLE, p, 2000.00 )
call RemoveLocation(p)
set p = null
endfunction

//===========================================================================
function InitTrig_test takes nothing returns nothing
set gg_trg_test = CreateTrigger( )
call TriggerRegisterTimerEventPeriodic( gg_trg_test, 0.50 )
call TriggerAddAction( gg_trg_test, function Trig_test_Actions )
endfunction
[/jass]
Using two variables:
udg_footy = unit
udg_vmod = visibility modifier

This is just test code, which is not really mean for use in a map. I'm just posting it here for reference.

yeah but what about for a game with 12 people realizing most have 56k and he said without jass in his original post

56k shouldn't matter, however out of 12 people, someone with a slower computer may be more affected. All in all, I still say using the unit's viewing distance against fog of war is the best choice. Using these Jass functions is not the best idea.

err well maybe there was another reason i was lagging, i had a trigger that said every 5 seconds make all units in area move to another area... it was extremely laggy
