The "light effect" {applying a filter depending on a unit's distance to a torch}

[Vincent]

I need help with a trigger, i tried it numerous times but it didn't work....

I need a trigger that every time a unit walks near a glowing torch they will gain vision(fade filter transparent white, slowly getting more vision) and the more they stray from it they will lose vision(black fade filter thing)

help pls!

It's possible with some mathematics but it would happen to all the players if one goes near the torch. Unless this is a single player map.

Maybe the night elf "Night Vision" (Cant remember the name) can do the work. I dont know if you can make it also work for days.

Else I think the human flare ability can do it. I remember vexorian do that in one of his spells

 

[Vincent]

Yes I'm doing it for a campaign and I'm planning to use the fade filter trigger but have little knowledge of it, also reduces they're acquisition range

I know! You can add to them the ability Chaos, alternate unit is the same just with more vision. When they leave give them a Chaos the other way around.

He's talking about fade filters. He want's the screen to be darker when you are far away from the torch and brighter when you're closer.
I'll start working on the system now.

EDIT:
Well the fading works so far but only with one unit and one torch. I think I can add some more torches but not units. The accusition range could be done too but the increased vision part will be a problem.

i think i just heard this before... It is the doodads or in a region you will change something to make it happen (I'm not sure) Train, you must

Use
custom script : if GetLocalPlayer() == udg_YourPlayer then
--stuff--
custom script : endif

Where YourPlayer is a global variable containing the player you want to make it fade for.

He's doing it for a campaign anyway so no need to worry about MUI and such really.

 

[MeKC]

If its for a campaign why then use the?

GetLocalPlayer()

 

[Element of Water]

I wasn't saying to him, I was saying to the person who is kindly making a system for it for him.

 

[Thrikodius]

Well since this is single player I see no need to add those custom scripts. They would only make me confused.

Here is an update with two torches. I'll add another one, then it will be pretty easy to put together a little tutorial for you in case you'd need it.

Make a trigger if it's single player that every .03 seconds checks the distance between the unit and the torch, and decide on how far a unit will be before he has 100% blackness. Use an arithmetic to change the transperency value as the distance changes.

I dont have the world editor on me but something like

Event - every .03 seconds of game time

For each integer variable [a] from 1 to [distance checking ranges amount]
Unit group - pick units matching condition [unit type = torch] within [distance checking range] of [hero] and do:
If [still checking] equal to true
Then set [transperency] to [distance arithmetic here]
Cinematic - fade filter apply with tint 0,0,0 with transperency [transparency] over 0 seconds
Set [still checking] equal to false
Else do nothing
(close the unit group thing and after still in loop)
Set [a] to [a] + [added range if torch not within that range]
close loop
If [still checking] equal to true
Fade filter 0,0,0 transparency 0%

I'll make this in the editor later on but it should work, and leaks can be removed from it easily.

 

[Thrikodius]

I guess I'm done. Four torches and the acquisition range is increased when your close to the torch.

Why only four torches? Make an indexing system and have 8192 torches if you want to...

I had made some modified on the map Thrikodius make .
Well , i used 20 dummy with each differ by 50 AOE of sight (assumed u used max sight is 1000AOE). Well , for bigger AOE of sight , create more dummy .

In this map I also add 2nd Deneration of fade , that is modified version for your long script , and also 3rd generation that is my version to make this system (well , I'm not using region center but unit position instead.)

Well , I don't think white mask is neccessary - -

Oh ya , my 3rd generation of this vision system can store up to 8192 touches (In case it not lagging = =). To plant more touch , go layer>unit>human>custom unit , There got a dummy different icon with eyes .

Haha , enjoy , any misunderstood , can pm me .

 

[Thrikodius]

Great. People working together to help a single user. If this would happen in real life the world would be a lot better.

 

[lord vendredi]

[Vincent]

Yeah that would be cool,
