Question about variables

[elm0]

If you have a point variable for a certain spell(triggered), let's say it's variable name is CasterPoint. Can I use the variable "CasterPoint" for another triggered spell? or will that cause bugs?

 

[BloodDrunk]

You can use same variables if the spell or action is instant without bugging up.
I usually call variables for instant actions or triggers "TempInt" or "TempPoint" or "TempUnitGRoup" or "TempReal" if you understand.
But for spells, I myself, create a variable that'll be used just for that spell.

 

[Greenwhy]

you can use the same variable for different spells as long as you don't need to save the value of that variable for later use.

 

[Rheiko]

Yes you can. but for some variable, you must destroy it first before using it for another trigger otherwise it'll leak.

You should not because you do not know how the implementation will blow up. Even if it is "instant", there may be interrupts. You should avoid global variables when possible anyway because then your code will be less instanceable, less recursion-capable. It's also better for debugging to separate it.

Ok, thanks for the help. +rep given to all of you

If I use different variables for every spell, would that increase the map size? Because I plan to make a lot of spells for my map and I'm trying to save up space

 

[Rheiko]

there's a method to make variables can be used more than once.
Dynamic Indexing for example

 

[BloodDrunk]

It will, but maybe for few kbs...
Unless you cr8 shitload of variables (I don't think u need shitload of it)

 

[elm0]

@Rheiko: Are you talking about arrays? sorry I'm new to the WE. anyway the variables I'm having trouble with are the points (Position of casting unit to be exact). I have a lot of spells that will be referencing to the pos. of the casting unit.

@the_blood: How big are variables? 'coz I might need a lot

Helpful Tutorial about variables
I don't know exactly, I think it depends on type of a variable.
I don't think amount of variables will impact your map size alot, so don't worry about it
Rather be careful about imports, don't import things you don't need or you import, don't use it anymore and then forget to delete it (I had troubles with that)

@the_blood: Ok, thanks again for helping.

Of course each new declaration increases the map size. But that's marginal in comparison to other assets of the map like imports.

Since you asked for it, I just looked up how much the globals block in my current project weights.

1.483mb for 25689 variables with a compression ratio of 15% -> 222.45kb -> 8.6 bytes per variable on average

and that's before wc3optimizer (you can only play maps with up to ~25k variables anyway) and includes initial values like string paths (which it can obv compress worse).

Here, WaterKnight gave you better answer

@WaterKnight: That solves my problem. I thought that variables would be about 30-80kb each hahaha. I really appreciate the effort. and wow! that's a lot of variables

If you use the editor, it creates additional editor-only files that take up a bit extra, which is why those should be opted out in your playable versions.
