I'm having the same issue, the tilemap's don't load or aren't accessible from the layers. Was this ever resolved?
As we have talked on Discord, you cannot layer_tilemap_get_id on dynamically created layers.
You will have to make a small script like
/// layer_tilemap_get_id_fixed(layer) var els = layer_get_all_elements(argument0); var n = array_length_1d(els); for (var i = 0; i < n; i++) { var el = els[i]; if (layer_get_element_type(el) == layerelementtype_tilemap) { return el; } } return -1;
Great to hear that this worked for the other person too. Due to some poor planning, it would have been a headache to try and send you a project that demonstrated the issue (since the extension is integrated into a big project at the moment), and given that nobody else seemed to have the same problem, I would much sooner assume it was my own fault rather than a problem with Game Maker, so I sort of gave up on it. But once again, YellowAfterlife comes to the rescue and sets us all straight <3 Thanks so much for the explanation and script.
