[JASS] Structs, timers, and variables o my

[Gost]

Alright so I am creating a projectile system and the main trigger is the one that moves them, each missile in flight is one instance of the struct and each instance of the struct contains these variables:

unit m          //Missile
unit c          //Caster
effect mdl      //Model(special effect)
unit t          //Target
real sp         //Speed
integer ID      //Event Id
real x          //Missiles X coord
real y          //Missiles Y coord
real tx         //Target X
real ty         //Target Y
real d          //Distance Between m and t
real f          //Missiles Facing
integer Level   //Level
real dmg        //Damage done

Right now this doesn't lag with multiple missiles in flight but I was wondering if the amount of variables in a struct would cause lag if it gets any higher. 'And secondly, would it be faster to store the target X and Y in the struct and update it every iteration, or just GetUnitX(t) every iteration (I believe I only require it once per iteration). Same with the missile X and Y.

Struct members are just global arrays, so no it won't cause any lag if there are more variables.
However if you are doing stuff with each of these variables per instance, it will be slower but not by much.
Depending on what you are doing with them.

'And secondly, would it be faster to store the target X and Y in the struct and update it every iteration, or just GetUnitX(t) every iteration (I believe I only require it once per iteration). Same with the missile X and Y.

Yes, it would be much faster to store it in a global and reference it.

There is a very small speed difference for storing vs accessing. Unless you are making a super complicated physics engine or something, do what you want.

Alright thanks
