Add ExprTimeLived

[MrScopes]

Problem

There's no current way to get the time lived of an entity

Solution

Added ExprTimeLived
time lived of %entities%
%entities%'s time alive
etc

Testing Completed

Test 1

		spawn cow at player:
			set {_cow} to cow
		wait 3 seconds
		send time lived of {_cow}
		send ticks of time lived of {_cow}
		send {_cow}.getTicksLived() # tested with the direct method
		wait 2 seconds
		send time lived of {_cow}
		reset time lived of {_cow}
		send time lived of {_cow}
		wait 1 second
		set time lived of {_cow} to 3 weeks
		remove 2 weeks from time lived of {_cow}
		send time lived of {_cow}
		add 1 week to time lived of {_cow}
		send time lived of {_cow}

expected off by a tick? I'm assuming since it doesn't wait for the cow to actually "start living"?
that's the reason I added the getTicksLived directly just to make sure this wasn't an error in the expression

Test 2 - edited provided example

		set {_target} to player's target entity
		send "%{_target}% has lived for %time lived of {_target}%"

		set {_spawned} to now

		spawn zombie at player:
			set {_boss} to zombie
		# start off with 1 tick lived instead of 0 to avoid custom effects running off spawn
		add 1 tick to {_boss}'s time lived
		while {_boss} is alive:
			wait 1 tick
			# update display name every tick with hp
			set display name of {_boss} to "Boss %{_boss}'s health%/%{_boss}'s max health%"
			# heal every second
			if mod(ticks of {_boss}'s time lived, 20) is 0:
				broadcast "heal every second. it's been %difference between now and {_spawned}%"
				add 1 to {_boss}'s health
			# push forward every 2 seconds
			if mod(ticks of {_boss}'s time lived, 40) is 0:
				broadcast "push every 2 seconds. it's been %difference between now and {_spawned}%"
				push {_boss} forward at speed 1
			# give strength every 10 seconds
			if mod(ticks of {_boss}'s time lived, 200) is 0:
				broadcast "strength every 10 seconds. it's been %difference between now and {_spawned}%"
				add potion effect of strength for 3 seconds to {_boss}'s potion effects

Test 3

Supporting Information

No breaking changes

Just out of curiosity I checked back and from what I can tell even in ancient versions of the game getTicksLived and setTicksLived has stayed the same

I will add the import when I get home and run some final tests then request review

Import and testing done, resubmitting approval request
test results are identical as expected


as expected it can be off within .05 seconds or 1 tick
