Perfect, you’ve done it again.

Thank you so much!

Thank you so much Dan! You’re such a huge help.

How could make the letters appear in a random order instead of in sequence?

Thanks

Tom

amazing that seem to have got it, thank you!

As if you haven’t help me enough, i’d like to try push it a little:

Could this be adapted so that it could be applied to text’s ‘animator’ property so each letter or word (you can choose) would flicker on in sequence or randomly (also choose). Ideally Id like to have a text layer that animates on/off based on the inPoint and outPoint (as it does so beautifully now) except there for would expression controls that allow you to change weather it flickers on as a whole, per word or per letter and also weather each word/letter flickers on in sequence or randomly.

Would this be terribly complicated?

Thanks again for your help Dan, really appreciated.

i’ll have a browse thanks ☺

On further play, It’s behaving a little odd. I’ve duplicated the text and adjusted the length and some of them work as expected and some just cut straight off… if i extend the time of the ones that cut off to a longer then they do the flicker… its seems random as to if they work or not.

Thanks

Dan you’re a frikkin genius. You’ve solved it yet again.

I understand the top half but If you’ve got a sec, could you briefly explain whats happening from ‘switch(f){‘ onwards? What is switch, break and case?

Thank you!

Tom

its the first step in a more complex function. sorry i should have clarified this.

Hey Valerie.

You could indeed add ‘+100’ to the scale but then the second circle will always be 100 larger than the first, whether the first circle is set to 0 or 10000. If this is what you’re after then i would use the following on the second circle’s scale:
(italics are your layers names)

[thisComp.layer(“Cirlce_1“).transform.scale[0]+100,thisComp.layer(“Cirlce_1“).transform.scale[1]+100]

to make it more controllable, id add a sider controller to your second circle and instead of typing “+100” in the expression, pickwhip to the controller. That way you don’t have to keep going in to change your value.

If however you want the size increase to be relative, id increase the second by a percentage, not a constant value.

what i would do is add a slider controller to the second circle and then in the second circle’s scale expression add the following:
(italics are your layers/slider names)

s=(thisComp.layer(“Cirlce_1“).transform.scale[0]/100)*effect(“2nd_Circle_Increase_%“)(“Slider”);
[thisComp.layer(“Cirlce_1“).transform.scale[0]+s,thisComp.layer(“Cirlce_1“).transform.scale[1]+s]

s will take the scale of the first circle, divide it by 100 and then multiply it by the slider controller value. This then means the slider can be used to input a percentage of the first circle’s scale. The second part will take the two scale dimensions and add the value of the slider. Now if you set the slider to 50, the second circle will always be 50% larger than the first.

This will means the second circle will scale RELATIVE to the first.

hope this helps!
