[General] Call Remove Location fast question

[Datnes]

Hi everybody,
I have just one simple question:
Have I remove locations every time i want to change the variables?
Or I can just change them like I want and then I just put the custom script (remove location) to the end of the trigger?

For example:

• Set Point = (Position of (Triggering unit))
• "Some action here"
• "Some action here"
• Custom script: call RemoveLocation(udg_Point)
• Set Point = (Position of (Picked unit))
• "Some action here"
• "Some action here"
• Custom script: call RemoveLocation(udg_Point)

OR:

• Set Point = (Position of (Triggering unit))
• "Some action here"
• "Some action here"
• Set Point = (Position of (Picked unit))
• "Some action here"
• "Some action here"
• Custom script: call RemoveLocation(udg_Point)

First method.

Variables are pointers, they don't actually hold the object as some may think it would. So if you reassign it, the old object will be left in memory. That's why you have to clear it before it gets reassigned, because once you set the variable to something else, you don't have access to that old object if you ever want to remove it later.

and that's why a map also may need only a maximum of 2-3 point variables, one for original
location, the other being the offset...and never use arrayed locations except if you're using
that location again and again using indexing systems...

What is the problem with using arrayed loc variables?

 

[mckill2009]

it's not a problem but it's slower or uses an extra pointer [?], therefore useless...

Ok thanks for help

You remove a location every time you do not need the location anymore.
