Change object property in code [lua]

I want to set an objects collidable property from “false” to “true” when a certain condition is met, does anyone know how I can do this? I’ve only been using tiled for a couple days ^.^’

What kind of condition? And couldn’t you implement such a condition in your game instead?

In general, there is currently no way to do anything based on certain conditions. This will definitely change once Tiled is scriptable, which is something I plan to work on later this year.
