[General] Move Instant vs. Get X/Y

[GywGod133]

Can you explain, what its the different by using Move Instant and Get X/Y?

For me, Move Instant mostly use to change the facing

 

[chobibo]

Move Instant moves the unit while Get X/Y retrieves their respective coordinates (X or Y position).

 

[Chaosy]

I think x/y is faster, but that's it..

 

[chobibo]

It is, Move Instantly checks pathing and writes to memory, that should make it execute longer than Get X/Y.

I think question is related to:

native SetUnitPosition takes unit whichUnit, real newX, real newY returns nothing

native SetUnitX takes unit whichUnit, real newX returns nothing
native SetUnitY takes unit whichUnit, real newY returns nothing

There are few differences, mainly:
- the first one is generally slower.
- it also performs somekind of stop-order-check and clears current order
- accounts for pathing, whereas the later two methods ignore it

Considering those, we could also say that SetUnitX/Y is kind of smoother than the position equivalent.

You can make sliding maps with with SetUnitX/Y.
You can also easily crash the game with SetUnitX/Y (there's no checking so you can push a unit out of map bounds)

Bannar explained it pretty well. But both have their advantages.

For teleport systems, where you usually don't need to check anything, SetUnitX/Y is better.

If you need to check for pathing and/or not want the unit be able to move itself while sliding, then you just can use SetUnitPosition.
Because as Bannar explained it gets "stop" order and it automatially checks for pathing.

But SetUnitX/Y is a lot fater, so it depends to your needs. Here a quote:

SetUnitPosition

~90% slower than SetUnitX & SetUnitY

Edit by WaterKnight:

Or you only want to change facing? There exists a function for it, only to change the unit's facing. In GUI and also a native for jass.

Unit - Make Unit Face ...

native SetUnitFacing takes unit whichUnit, real facingAngle returns nothing

@IcemanBo
maybe its good to use Get X/Y

Or you only want to change facing?

its only a example of what use of move instant

THANKS TO ALL

Don't mix Get with Set.
GetUnitX(unit) returns the current x-coordinate of the unit.
SetUnitX(unit, real) sets the unit to a new x-coordinate.
