Common Mistakes

Using MeshRenderer instead of Mesh

Trying to create a GameObject instead of a Mesh

We create a new Mesh by calling new Mesh(). MeshRenderer is a component, not a mesh object.

Complete the code to assign the mesh to the MeshFilter component.

Unity

GetComponent<MeshFilter>().[1] = mesh;

Drag options to blanks, or click blank then click option'

Common Mistakes

Assigning to material instead of mesh

Using renderer property which belongs to MeshRenderer

The MeshFilter component has a mesh property where we assign the Mesh object.

Common Mistakes

Adding MeshFilter instead of MeshRenderer

Trying to add Mesh or Material as a component

To render the mesh, we add a MeshRenderer component to the GameObject.

4fill in blank

hard

Fill all three blanks to create vertices and assign them to the mesh.

Unity

Vector3[] vertices = new Vector3[] { [1], [2], [3] };
mesh.vertices = vertices;

Drag options to blanks, or click blank then click option'

Anew Vector3(0, 0, 0)

Bnew Vector3(1, 0, 0)

Cnew Vector3(0, 1, 0)

Dnew Vector3(0, 0, 1)

💡 Hint

Common Mistakes

Using the same vertex twice

Using invalid Vector3 syntax

Vertices define points in 3D space. Here, we create three points at (0,0,0), (1,0,0), and (0,1,0).

5fill in blank

hard

Fill all three blanks to define triangles for the mesh.

Unity

int[] triangles = new int[] { [1], [2], [3] };
mesh.triangles = triangles;

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using indices out of range

Not providing exactly three indices

Triangles are defined by indices of vertices. Here, the triangle uses vertices 0, 1, and 2.
