If your floor really is a single solid object the next thing i d check is that the physics loop is running at a high enough frequency that the player can t fall too far into the object before the next tick.
Imported asset falls through floor unity.
The mesh does not align correctly to the character the character fell through.
But the imported fbx object as prefab falls down as game is started like object with physics component.
How to stop falling through floors and colliders in unity recently i have been working on a 2d platformer which uses the inbuilt unity physics and rigidbodies.
I have not added rigidbody to the object.
How to set up collision.
It doesn t work.
On the object i added a rigidbody and it already has a box collider.
Sweet then i added a rigidbody to my dude and added gravity.
He kept falling trough the floor.
However my object falls through the floor.
I m using the official unity tutorial.
I imported the robot kyle asset from unity 3d.
If your first person character falls through the floor of your game level you may need a terrain collider.
I created a plane in unity.
I added a terrain object and gave it a texture to make my floor.
I want to make a bouncing ball effect.
One of the challenges i ran into was that when the player moved above a certain velocity it would sometimes pass through colliders.
Then added a rigid body the character fell through the plane i then added a mesh collider and attached the mesh for the character to the collider.
This happens most often when you fall between the cracks on badly modeled joined terrain due to floating point rounding errors.
I figure i needed to add a terrain collider and then on the trigger move the rigidbody with a vector force of up.
It keeps falling through the floor.
Model created in unity eg gameobject create object cube is not falling down in y axis.
