Expression writing
Hi everyone,
Ive been studying expressions and have noticed that at the end of certain expressions there is [x,y] at the end of an expression.
I want to know the significance of putting [x,y] or [xPosition,yPosition,zPosition] at the end?
For example:
var x = transform. position[0];
var y = Math.sin(time);
[x,y]Or
var xPosition = transform.xRotation;
var yPosition = transform.yRotation;
var zPosition = transform.zRotation;
[xPosition,yPosition,zPosition ] -

Hi,
In the first lines, you declare and give a value to your variables (that’s why you use “var” before, although it isn’t obligatory in expressions).
Then, in the last line(s), you use these variables to assign a value to your property (position in your cases). The brackets are there to express a multi-value property (x,y or x,y,z for position / x,y,z rotation, etc…)
Other properties (like 2d rotation) only take one value, so you don’t use the brackets.Hope this clarifies things a bit for you ????

This makes sense, thank you so much!
