How do I drag and keep an object’s custom collision mask inside another object’s custom collision mask? I’m trying to make an Isometric game where you have a floor that can change size (meaning multiple instances of the floor object connected with each other) and you have an item on the floor that y…

Can you post a image of the larger picture? How the scene is setup. Also, the events that you’re currently using. It might be easier to add boundary objects to prevent movement. Or maybe use pathfinding instead of dragging. Or maybe, use a point on each side that detects whether there’s a tile? It…

[image] Help with isometric movement How do I...? I’m trying to move a sprite in a four way isometric movement, each floor tile has four variables which determines which way it can travel, I’ve got the sprite moving but he still wonders off track slightly, also…

I assume this is what you mean by the larger picture? keep in mind the floor can change size (expand and unexpand) it could also be not even i.e 2x8 or 8x2. I managed to make it work with a single instance with this code: Adding boundary objects but how am I going to make them adapt to the changin…

I’m not sure what part of this can help me? I don’t think my issue is similar to his 100% !

Ok ….have you tried using four custom points and checking point inside object? Id found that thread as I was curious to see whether there was an isometric auto tiling extension and that thread came up. You could also possibly use an array and store the tiles and check that. I’d need to do this in o…

Yep, I am currently using 4 custom points but it only works with a floor that is made with one instance of an object not many instances I gave the code in one of the replies if you want to check it. As for the array option I’ll try but the issue is always I will expand and unexpand the floor and it …

what’s the mechanic you had in mind for changing the size of the floor? this kind of works for point inside approach… but its a bit of an and or not headache! Its a tricky one due to it being dragged. so i used angle to cursor as a condition to check which way youre dragging it ![Screenshot 2026-0…

the mechanic for changing the size of the floor is like pressing 4 buttons to expand/unexpand from either bottom left or bottom right. It doesn’t matter, I just need it to work with multiple instances of the floor! It is a must that it drags smoothly and slides smoothly on edges. I wonder if you tes…

Yes It works with multiple instances there’s two above. but I just woke up thinking ….what if all it needs is point cursor is inside floor.

i worked on it a bit. it does work just checking whether the cursor is inside the floor but its slightly better with points and the angle check. heres the example project with multiple floor tiles [image] Absent Sort | Play on gd.games [Screenshot 2026-08-17 081…
