You need to remove the flag which is associated with that particular wall object in the collision map (RegionMap in-case of Matrix), assuming you are using Matrix, you can use the following code:
But that process should be automatically done if the object was properly removed. Try preventing them from being clipped in the first place maybe, in other words, try preventing them from being spawned instead of removing them after being spawned? Or even better remove that object from the locations map (lsx_sy file) if you have an encoder.Code:World.getRegion(...).unclip(object, object.getXInRegion(), object.getYInRegion()); or World.unclip(object or tile);
