Any way, i have another queation.
At some point in the expression he used the code

hsl[0] + = .5;

And later he explained:
“+ = .5” means add .5 to whatever the value already is.

Im slightly confused,
What is tge diffrence bewtween the usual
Value=+.5?

[Assaf Goldlust]

Well,this sucks

[Assaf Goldlust]

wait, so why in the book its looks like this?

[Assaf Goldlust]

Thanks,
but is there a reson for why you still need to user propertyindex?

why is it not possible to just write:

effect("4-Color Gradient").param(thisProperty, - 2).valueAtTime(time - .5)

thisComp.layer(thisLayer, + 1).transform.rotation . valueAtTime(time − .5)
why there is a need for a comma between the “thisLayer” and the “+1”

yes i did this is why im cofused about it. what did he ment when he was saying that the second statement is the one after effect use to controll the expression.

and that the first statement only tells the computer to store a variable in a value?

P.S im posting the screenshots becuse i did wrong previusly

[Assaf Goldlust]

An expression just applies the value of the last statement executed to the property hosting the expression. So, these three expressions applied to the rotation property have the exact same result:

controller=transform.opacity;
controller

or,

controller=transform.opacity;

or,

transform.opacity;

its kind of sounds tome like its at odds with what he saids.

im uploading the part were he speaks about it. maybe it would help understanding becuse if to be honest im not sure i explained it right.

I guess Ae expressions were created to do that, not sur it works in a script ?

not trying to be rude but that line had me wonder if you are sure about what your saying.
or simply making guesstimations

[Assaf Goldlust]

i tried the whole thing a again. i have noticed something weird
when i preform the track with no prespective its looks fine in after effect.
however its keeps the accuracy beneath acceptable. level (around 64%)

any idea the hack is happening?

[Assaf Goldlust]

i think i better show you.
