Gravity Slide System Trigger

Made a quick system that makes all units slide down hills and stuff.

The trigger:

Trigger:

SlideSystem

Events

Time - Every 0.05 seconds of game time

Conditions

Actions

Unit Group - Pick every unit in slideg and do (Actions)

Loop - Actions

Set u = (Picked unit)

Custom script: set udg_sliderx = GetUnitX(udg_u)

Custom script: set udg_slidery = GetUnitY(udg_u)

Set slidep[0] = (Position of u)

Custom script: set udg_sliderz[0] = GetLocationZ(udg_slidep[0])

-------- --- --------

Set slidep[1] = (slidep[0] offset by (32.00, 0.00))

Custom script: set udg_sliderz[1] = GetLocationZ(udg_slidep[1])

Set sliderx = (sliderx - (sliderz[1] x 0.10))

Custom script: call RemoveLocation(udg_slidep[1])

-------- --- --------

Set slidep[1] = (slidep[0] offset by (-32.00, 0.00))

Custom script: set udg_sliderz[1] = GetLocationZ(udg_slidep[1])

Set sliderx = (sliderx + (sliderz[1] x 0.10))

Custom script: call RemoveLocation(udg_slidep[1])

-------- --- --------

Set slidep[1] = (slidep[0] offset by (0.00, 32.00))

Custom script: set udg_sliderz[1] = GetLocationZ(udg_slidep[1])

Set slidery = (slidery - (sliderz[1] x 0.10))

Custom script: call RemoveLocation(udg_slidep[1])

-------- --- --------

Set slidep[1] = (slidep[0] offset by (0.00, -32.00))

Custom script: set udg_sliderz[1] = GetLocationZ(udg_slidep[1])

Set slidery = (slidery + (sliderz[1] x 0.10))

Custom script: call RemoveLocation(udg_slidep[1])

Custom script: call SetUnitX(udg_u, udg_sliderx)

Custom script: call SetUnitY(udg_u, udg_slidery)

Custom script: call RemoveLocation(udg_slidep[0])

This is the main trigger, does all the sliding.

Trigger:

RemoveSlider

Events

Unit - A unit Dies

Conditions

((Triggering unit) is in slideg) Equal to True

Actions

Unit Group - Remove (Triggering unit) from slideg

And of course to remove the units from the group.

The problem is the lag this generates - tested 400 units running to a point using this system and no system, with an FPS difference of about 5 (this is quite something for slower, older pcs).

Is there any way that I can optimize this code? I looked through jass craft for a GetUnitZ function, but couldn't find.

Yes!! doing it in JASS :P

GetUnitZ doesn't exists, you have to use GetLocationZ()

grim001	The most important thing for you to change if you want to drastically improve performance is to stop creating and destroying locations. Use one global location, and recycle it for every time you need to use GetLocationZ.

Thanks grim001, I'll give that a try.

moyack, the idea behind this system being in GUI is that it'll be easier to use for more people - generally when I make a map and forget about it, others pick it up on Battle.net or epicwar.com and continue it, so I like to make my triggers easy to use.

Another thing, I think there are a few JASS systems that include gravity sliding... I'm too GUI to use them.
