You can create as many custom Physics MaterialA physics asset for adjusting the friction and bouncing effects of colliding objects. More info
See in Glossary assets as you need, and apply them to collidersAn invisible shape that is used to handle physical collisions for an object. A collider doesn’t need to be exactly the same shape as the object’s mesh - a rough approximation is often more efficient and indistinguishable in gameplay. More info
See in Glossary in your sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary.
Several colliders can have the same Physics Material asset assigned to them, and you can set a project-wide default to apply new default settings to all colliders in the project.
To create a Physics Material asset, go to Assets > Create > Physics Material. By default, Unity places new Physics Material assets in your Assets
directory.
You can create as many custom Physics Material assets as you need. Physics Material assets have the file extension .physicMaterial
.
To apply a Physics Material asset to a collider:
Alternatively, you can click and drag the Physics Material asset file directly from the Project windowA window that shows the contents of your Assets
folder (Project tab) More info
See in Glossary onto the target collider’s Material field.
Each collider can only have one assigned Physics Material asset at a time. You can assign the same Physics Material asset to multiple colliders.
You can use a custom Physics Material asset to replace the project-wide default settings. Unity applies the project-wide default settings to any collider that does not have an assigned Physics Material asset.
To change the default Physics Material values: 1. Create a Physics Material asset and configure it to the default settings you want for the project. 2. Go to the Physics Settings (Edit > Project Settings > Physics). 3. In the Default Material property field, select the picker icon. 4. Select the Physics Material you want to use.
