Hey all,
I am using the 2D Grid Macro to spawn a grid of vertical cylinders Blueprints, where each of them has another 2D Macro to spawn another Blueprint of a light-cube,
the result looks like this:
This is my BP to spawn the cylinders:
and within each cylinder there is this BP to spawn the light cubes:
Now I am using a timeline to turn the light cubes on/off in various ways.
I made sure to catalog each Blueprint with its relative position (I think), my current goal is to light up the cubes from inwards outwards,
So I have to calculate for each lightcube Blueprint its relative position in the on-off timeline. For some patterns it’s easy to calculate like up-down or left-right,
but to calculate inwards/outwards I am a bit stuck.
Is there an efficient way to calculate this?
My controls are
1- Tube amount (equal x/z tubes)
2- Light Cube amount (spawns on the Y axis)
Thanks a lot in advance

Hola 
They’re blueprints, right? Why not each BP to calculate it’s distance from the center, just using the distance vector node?
Sounds perfect actually, how would one use that in this case?
My timeline is 1 second, so I will need to calculate the distance and turn that into a relative position from 0-1 where 0 is the closest to the center, 1 is the furthest?
Is it a central timeline, or does each have it’s own?
What’s supposed to happen? At 0 only the center ones lit, and at 1 only the outer ones?
Each BP has its own timeline.
So the position of that cube’s timeline should be from 0-1, 0=the closest cubes to the center, 1= the furthest
Then I suppose I’ll get this effect of the cubes turn on/off in chase mode, outwards
Thanks as always
Something along these lines
Amazing! thank you so much, I just adapted it to the Set Playback Position method, so they all run at the same time,
Here is the result:
Thank you so much much easier this way !
Hang on, not quite right…
Yes, that’s what I meant, playback position
perfect, I just added the clamp node cause I needed the result to be 0-1, as my timeline is 1 second.
You are always to the rescue thank you
Of course, you’re right. It was just a general concept
