CLAVISANIMA'S PROFILE

I managed to get it working when moving forwards and backwards by applying your idea when the player is facing certain directions: I used a conditional branch that reads the terrain ID (if terrain ID is 0/ not 1, the player will not move). This branch is only used when the player is facing certain directions whilst moving the box. For example, if the down button is pressed, the conditional branch is only used for when the player is facing up and vice versa when up was pressed. This allowed the player to move forward with the box if they were standing one tile away from the passable tile.

I still have yet to try this out when moving sideways, but I'm sure it will work if I apply the same principles.
Edit: Yup, it definitely works sideways too. My only problem now is that there's a delay when pulling.
Edit 2: I realised that the delay was caused by a 'wait until movement finishes' when the player is pulling the box. Everything works great now :)

Here's a snippet of the event for anyone who's interested:

Hi again,

I was wondering if there was a way of making sure that the player stops moving when the box/object is unable to move.

So here's the scenario: I have coloured boxes that only move along paths of the same colour (red boxes move on red paths, blue boxes move on blue paths). The boxes cannot move out off the path. I was able to get this to work using a TheoAllen's Passability Terrain Script.

The problem is that the player will still be able to move in the direction that the box cannot move. I could make contact events where the player can't move in certain directions if the box is unable to move, however I think that method would be inefficient.

I attempted to make it so that the player stops moving when they step on a certain region, however, this makes it so that they cannot move the box at all.
