In Construct Classic the platform behavior has ignore list actions that you can use to select which solids you want to have collisions with and which solids to ignore collisions with, but this feature is not in Construct 2 or 3.
I'm suggesting this feature should be added for all movements. (platform, bullet, car, 8 direction) and for all objects with collisions.
To clarify, I'm talking about the feature used in this example for a staircase that the player can walk on, but enemies can't walk on:
(requires construct classic to open)
and used in this screenshot:
A feature for filtering collisions with solids using tags shipped in r123.
