Snippet DayNightRequirements

[Azlier]

This little script lets you easily create abilities that only work at day or at night.

Just follow the unusually complicated import instructions, and you're good to go. Simply adding a dummy to an ability's techtree requirements will make it day or night specific.

Requires DNE.

//  What is DNR?
//         - DNR allows the quick and easy creation of abilites that only work at day or night.
//
//  How to use:
//         - For each ability that requires day or night, add the respective dummy
//           created by the system in the ability's techtree requirements.
//
//  How to import:
//         - Create a trigger named DNR.
//         - Convert it to custom text and replace the whole trigger text with this.
//         - Save the map, and close it.
//         - Reopen the map and remove the exclamation marks from the start of the two lines below this one.

The demo map will turn the clock to night when "-night" is typed, and I wonder what "-day" could possibly do...

I'm pretty sure Neutral Passive could have an evasion ability that only works at night...

 

[Azlier]

>lol
What's so funny?

Shadowmeld only works at night, yes. What does that have to do with anything?

 

[Jesus4Lyf]

>[LJASS]private player Holder = Player(15)[/LJASS]
This will fail for Neutral Passive, no?
Should be able to give any player 100% evasion only at night or something.

 

[Azlier]

Ah, so that's what you're saying. There's really no way other than making it a configurable, which I can do.

One player HAS to have the units.

 

[quraji]

For some reason this looks familiar.

Good Idea, Azlier!

...
private function Init takes nothing returns nothing
    local integer i = 11
    local player p = Player(15)
    local trigger t = CreateTrigger()
    
    loop
        set DayU<i> = CreateUnit(p, DAY, 0, 0, 270)
        set NightU<i> = CreateUnit(p, NIGHT, 0, 0, 270)
        ....
</i></i>

p = ?

 

[quraji]

        static if STARTS_DURING_DAY then
            call SetUnitOwner(DayU<i>, Player(i), false)
        else
            call SetUnitOwner(NightU<i>, Player(i), false)
        endif</i></i>

->

        if (GetTimeOfDay() >= DAWN_TIME and GetTimeOfDay < NIGHT_TIME) then
            call SetUnitOwner(DayU<i>, Player(i), false)
        else
            call SetUnitOwner(NightU<i>, Player(i), false)
        endif</i></i>

Remove the units and recreate them. Or morph them into eachother when day/night ticks.

 

[Azlier]

>Or morph them into eachother when day/night ticks.

Almost perfect. Now if only that was instant, and does that work outside the map bounds?

>if (GetTimeOfDay() >= DAWN_TIME and GetTimeOfDay < NIGHT_TIME) then

That won't guarantee it'll work. Sadly.

Odds are that this library will run before anything that sets the time.

>p = ?

Fail on my part.

Performing fix's.

 

[Jesus4Lyf]

>Odds are that this library will run before anything that sets the time.
Use a 0 sec timer. C'mon, Azlier.
No one casts an ability "immediately". Wait, wouldn't your triggers detect that the game time has changed and update the status of the units?...

 

[Azlier]

>Use a 0 sec timer. C'mon, Azlier.

And what happens if THEY use a 0 second timer?

 

[quraji]

I tried to test it and GetTimeOfDay() returns 0.000
Incidentally, this is also the time my map starts at...

How do you set the time a map starts at
(without using the function, of course)

 

[SanKakU]

this is very cool, but uhm...are you going to add spells that can be cast night or day but are stronger(possibly by having secondary effects) at day time or night time?

in other words, make a peon with a fire breath attack and ice attack that casts any time of day, but the ice attack if casted at night slows the targets, but the fire attack if cast at day damages the targets over time...just as an example.

not only that, i'd like to see your system prepare hero abilities without bugs.

 

[Jesus4Lyf]

this is very cool, but uhm...are you going to add spells that can be cast night or day but are stronger at day time or night time?

That should be coded in the spell. The most this could do is provide IsDay/IsNight [LJASS]boolean[/LJASS]s.

are you serious? if that's the case, his system is a total joke, but hey, i can't say mine looks better than his...but that doesn't mean it's not better, because it is...
maybe that isn't so complicated...but i don't remember
i do remember for sure the hero ability learning bugs, though...at least make sure you find that the system prepares hero abilities without bugs.
if it can do that, then i'll be impressed.

 

[Jesus4Lyf]

I'm sorry, did simplicity offend you?

if IsNight then
    call Deal200Damage()
else
    call Deal100Damage()
endif

What's your idea for that?

 

[SanKakU]

ok, right, that part of it is easy...but what about the ability learning?

 

[Jesus4Lyf]

>but what about the ability learning?
What do you mean?
