Removing leaks in Lua

[DarkIllidan]

Hi I am pretty new to LUA and I would love to know how can I do some things in LUA that I know in JASS like:

• Custom script: call RemoveLocation(udg_Point)

• Custom script: call DestroyGroup(udg_GroupVar)

• Custom script: call DestroyForce(udg_PlayerGroup)

Thank you for helping out!

Remove the "call" keyword.

Thank you for answering m8!

• Custom script: RemoveLocation(udg_PointVariable)

Doesn't seem to work. Ignores all triggers beneath it.

Do you have another location variable named udg_PointVariable? In that case, just change it back to RemoveLocation(udg_Point). In case that still doesn't work, enclose the call within an xpcall function, which will help you determine if and what errors are occurring when using said function. The xpcall line should look like this: xpcall(RemoveLocation, print, udg_Point)

Creating and removing a global variable:

• Set Variable TempPoint = (Center of map)
• Custom script: RemoveLocation(udg_TempPoint)

Creating and removing a local variable:

• Custom script: local TempPoint = Location(0, 0)
• Custom script: RemoveLocation(TempPoint)

udg_ is a prefix that tells the code you're talking about a global variable.

Getting started with Lua scripting in Wc3 maps

I'm not quite sure how to get started with a map using Lua as the primary scripting language. My initial method for exploring Jass was often creating a trigger and converting to custom text, but that doesn't seem to work with the scripting mode set to Lua. Does anyone know of...

Can you explain me how works Lua?

I'm getting started in Lua after 4 months of learning Jass and vJass, I know some basics things like I can't use the words "call", "set", "takes" or "returns", for code functions I can do it inside of the current function, the IDs needs FourCC and all the variables can have any type of value, I...

Thank you both for helping out.

I'll be more precise.
I made a Global Variable and then this triggers:

• Set VariableSet Cinematic1WalkDemon = Cinematic1DemonMoveTo1 <gen>
• Unit - Order Demon Hunter 0032 <gen> to Move To (Center of Cinematic1WalkDemon)
• Wait 9.00 seconds
• Custom script: RemoveLocation(udg_Cinematic1WalkDemon)

Ignores all triggers beneath:

• Custom script: RemoveLocation(udg_Cinematic1WalkDemon)

Do you have another location variable named udg_PointVariable? In that case, just change it back to RemoveLocation(udg_Point). In case that still doesn't work, enclose the call within an xpcall function, which will help you determine if and what errors are occurring when using said function. The xpcall line should look like this: xpcall(RemoveLocation, print, udg_Point)

When I use

• Custom script: xpcall(RemoveLocation, print, udg_Cinematic1WalkDemon)

I get:

I think I resolved the Issue by changing the Variable from Region to Point. I'll check back later.
Ye this solved the issue.

Yeah, Regions are not Points (locations). Your trigger should look like this:

• Set Variable SomePoint = Center of Cinematic1WalkDemon <gen>
• Unit - Order Demon Hunter 0032 <gen> to Move To SomePoint
• Wait 9.00 seconds
• Custom script: RemoveLocation(udg_SomePoint)

Your preplaced Regions can remain active throughout the entire game, you don't have to worry about removing or cleaning them up.
