Can someone help me with collisions?

[past jay]

Good afternoon, I’m working on a personal project to create an RPG Tabletop, similar to the system used by Tabletop Simulator. I’m currently facing an issue with the collision of my tokens.

I want the tokens to move according to Terrain Collision and automatically adjust when passing through gaps or small-to-large elevations. However, in my tests, the Objects (tokens) either fall off the collision platform or pass through it when moving uphill.

The system I’m using relies on a Raycast to move and drag the Objects with the mouse. Is there any Rigidbody configuration or a way to adapt my script to prevent them from going through the ground or failing to move properly over elevated/sloped surfaces?

The code is an adaptation of the DragObject/GrabObject idea, but designed so that the Token does not tip over or fall.

do these need to be simulated rigidbodies?

also a video of the issue would help

Here’s a video, the collision only works with the initial Box Collider. When I try to move the token to small elevated areas or across the terrain itself, the token falls through the ground object (Floor).

seems to have more issues than just falling through the floor

also you didn't show it falling throught the floor

I think you need to narrow in on your problem(s)

the reason it would fall through the floor would be its being placed under the floor
