Tree Revival System

07-03-2009, 10:48 PM

A simple tree revival system. After searching I hadn't found one (no, the outdated tutorial doesn't count), so i decided to make my own.

Requirements:
TimerUtils, by Vexorian.
IsDestructableTree by PitzerMike

Code:

library:

library TreeRevival initializer Init requires TimerUtils, DestructableLib

globals
    //**Configuration***********************
    private constant boolean BIRTH_ANIMATION = true
    private constant real REVIVAL_TIME = 30.
endglobals

private function Conditions takes nothing returns boolean
    return true
endfunction
//**************************************
    
globals
    public trigger Trigger = CreateTrigger()
endglobals

private struct Data
    destructable d
endstruct

private function Enum takes nothing returns nothing
    call TriggerRegisterDeathEvent(Trigger, GetEnumDestructable())
endfunction

private function TreeFilter takes nothing returns boolean
    return IsDestructableTree(GetFilterDestructable())
endfunction

private function ReviveTree takes nothing returns nothing
    local timer t = GetExpiredTimer()
    local Data d = GetTimerData(t)
    call DestructableRestoreLife(d.d, GetDestructableMaxLife(d.d), BIRTH_ANIMATION)
    call ReleaseTimer(t)
    call d.destroy()
    set t = null
endfunction

private function Actions takes nothing returns nothing
    local timer t = NewTimer()
    local Data d = Data.create()
    set d.d = GetDyingDestructable()
    call TimerStart(t, REVIVAL_TIME, false, function ReviveTree)
    call SetTimerData(t, d)
    set t = null
endfunction

private function Init takes nothing returns nothing
    call EnumDestructablesInRect(bj_mapInitialPlayableArea, Filter(function TreeFilter), function Enum)
    call TriggerAddAction(Trigger, function Actions)
    call TriggerAddCondition(Trigger, Condition(function Conditions))
endfunction

endlibrary

Rising_Dusk	IsDestructableTree Is this a new native in 1.24? It doesn't show in my old common.j

busterkomo	It's included in one of the required libraries.

Rising_Dusk	Oh, duh, I'm brilliant.

Rising_Dusk	You leak a timer reference in ReviveTree. You leak a timer reference in Actions. As a system, it needs an image for the thread's thumbnail. Otherwise, this is very simple, but I very much like it that way. This does not need to be complicated, and truth be told, that old tutorial is stupid for being a tutorial anyways. Having a system handy for direct use is much better.

emjlr3	what if we dont want trees to revive if units/heroes are near by, thus traping them in...?

Rising_Dusk	Guess you could make the conditionfunc of the trigger a configuration condition for users to play with. Then just move the current conditionfunc to being an actionfunc.

busterkomo	Changes made.

moyack	This can't be considered a system due it doesn't use abilities or other things different of trigger editor, it's more a script. But as a script, it's nice.

The difference between a script and a system is ethereal, really, but some key differences do exist. A script is something lower-end than a system, since it may be required by other libraries also in the database. Damage Detection Systems these days do not carry OE dependencies anymore either, yet because they are so high-level, they are systems.

This is an end-product of scripts, nothing will ever require it. This makes it a system.

Anyways, approved.

DreamRaider	I don't like the idea how trees somehow instantly grow. It should be a progressing growth little by little over time.

emjlr3	i thought they did...

The boolean for playing the birth animation does just that. If you want to slow down the birth animation, you'll need to edit the model (Since SetDestructableTimeScale does not exist).

Flame_Phoenix	You have to be kidding me. I have a mini-system that does exactly this sort of things in my map and it isn't half complex ... according to Cohadar systems should be hard things to make. I agree with him, IMO this should be a script ... Anyway seems a good modular work, well done...

Last I checked, Cohadar doesn't approve resources.
