How does a polygon Collider work in Unity?
The Polygon Collider__ 2D__ component is a Collider for use with 2D physics. The Collider’s shape is defined by a freeform edge made of line segments, so you can adjust it to fit the shape of the Sprite A 2D graphic objects.
How do you edit a collider in Unity?
Details. The Collider can be edited manually but it is often more convenient to let Unity determine the shape automatically. You can do this by dragging a Sprite Asset from the Project view onto the Polygon Collider 2D component in the Inspector. You can edit the polygon’s shape by pressing the Edit Collider button in the Inspector.
How do you edit a polygon in Unity?
You can edit the polygon’s shape by pressing the Edit Collider button in the Inspector. You can exit Collider edit mode by pressing the Edit Collider button again. While in edit mode, you can move an existing vertex by dragging when the mouse is over that vertex.
Why does my polygon Collider not update every frame?
The issue most likely has to do with the skin & bone animation. The polygon collider will not update itself every frame while the sprite is animating.
Is the polygon Collider connected to the platform effector?
My platforms have polygon collider 2d s attached to them (which is connected to a platform effector if that is worth mentioning).
How to make a polygon Collider behave as a trigger?
See in Glossary, such as friction and bounce. Tick this box if you want the Collider to behave as a trigger. Whether the Collider is used by an attached effector or not. Tick this checkbox if you want this Collider to be used by an attached Composite Collider 2D.
Why does the collider 2D stay the same size?
If you don’t enable Auto Tiling, the Collider 2D stays the same shape and size, even when the Sprite’s dimensions change. The local offset of the Collider geometry.
When is a polygon Collider used by an attached effector?
Whether the Collider is used by an attached effector or not. Tick this checkbox if you want this Collider to be used by an attached Composite Collider 2D. When you enable Used by Composite, other properties disappear from the Polygon Collider 2D component, because they are now controlled by the attached Composite Collider 2D.
How is a box Collider attached to an empty object?
The empty object has a rigidbody (3d) attached to it as it needs to have one in order to use the configurable joint component ( note: I move my player around using this 3d rigid body).The player body however, a child to the graphics, has a box collider 2d attached to it as it after all it is a 2d game and has to collide with other 2d objects.
GitHub – NotWoods/unity-polygon-2d-editor: Uses the collider of a PolygonCollider2D to generate a mesh for a Unity GameObject. Uses the PolygonCollider2D collider to generate a mesh for a gameobject, letting you draw polygonal platforms in the Unity edtior via the Edit Collider button.
How can I edit a collider in Unity?
The local offset of the Collider geometry. Non-editable information about the complexity of the generated Collider. The Collider can be edited manually but it is often more convenient to let Unity determine the shape automatically.
Can a polygon Collider be modified at runtime?
IMPORTANT: If you want to modify Polygon Colliders based on the shape of a sprite at runtime make sure you set the sprite to “Advanced” and check off “Readable”. If you don’t do this the collider will work in the editor but not in any builds.
