Move on local Axis Expression

Hi Everyone!

I can't find out, how to move a solid on its local axis using expressions... I played with toGlobalVec but it didn't work for me... Can someone help please?

Thanks!

Edit: working in 3D Space...

Hey Dan, thanks for your answer!,

That worked for me, i'm not sure what i did wrong Yesterday... Thanks!

I have a follow up question though: is it possible, to move a layer on ANOTHER Layers local axis?

I have two solids in 3D Space, both of them have their anchor at 0,0,0. I want one layer to always be positioned at the Master Layers upper right corner. i'll post my code below. the problem with it is, that when i rotate the slave layer around its y-axis, it rotates around the Master Layers Anchor rather than its own... So i would like to try and move the Slave layer on the MASTER layers local x-axis.

How would you approach something like this?

MasterLayer = effect("Master Layer")("Layer")

MasW = MasterLayer.width

MasterWidthPercent = MasterLayer.transform.scale[0];

MasterWidthPixel = MasW/100* MasterWidthPercent;

Xs = transform.scale[0];

x =MasterLayer.transform.position[0]
y = MasterLayer.transform.position[1]
z = MasterLayer.transform.position[2];

[x,y,z] + toWorldVec([MasterWidthPixel/100* Xs ,0,0])
