How to create a Mesh from Code | Unity

[@cjtodd77]

This is awesome. Unfortunately the code isn't in the description. I am curious about the movement you created.

public class SoftCube : MonoBehaviour { protected MeshFilter MeshFilter; protected Mesh Mesh; public float UpDownFactor = 0.1f; public float UpDownSpeed = 6f; public float LeftFactor = 0.3f; public float LeftSpeed = 3f; public float LeftOffset = 2.3f; public float StrectFactor = -0.1f; public float StrectSpeed = 6f; // Start is called before the first frame update void Start() { Mesh = new Mesh(); Mesh.name = "NewMesh"; Mesh.vertices = NewVertCube(); Mesh.triangles = NewTrisCube(); Mesh.RecalculateNormals(); Mesh.RecalculateBounds(); MeshFilter = gameObject.AddComponent(); MeshFilter.mesh = Mesh; } private Vector3[] NewVertCube(float up = 0f, float left = 0f, float stretch = 0f) { return new Vector3[] { //Bottom new Vector3(-1,0,1), new Vector3(1,0,1), new Vector3(1,0,-1), new Vector3(-1,0,-1), //Top new Vector3(-1 - stretch + left, 2 + up, 1 + stretch), new Vector3(1 + stretch + left, 2 + up, 1 + stretch), new Vector3(1 + stretch + left, 2 + up, -1 - stretch), new Vector3(-1 - stretch + left, 2 + up, -1 - stretch), }; } private int[] NewTrisCube() { return new int[] { //Bottom 2,1,0, 2,0,3, //Top 4,5,6, 4,6,7, //front 2,7,6, 2,3,7, //back 4,0,1, 4,1,5, //left 0,4,3, 3,4,7, //right 1,2,6, 1,6,5, }; } // Update is called once per frame void Update() { Mesh.vertices = NewVertCube(Mathf.Sin(Time.realtimeSinceStartup * UpDownSpeed) * UpDownFactor, Mathf.Sin(Time.realtimeSinceStartup * LeftSpeed + LeftOffset) * LeftFactor, Mathf.Sin(Time.realtimeSinceStartup * StrectSpeed) * StrectFactor ); } }

Thanks

// Optional: Change color over time for extra aesthetics private void OnRenderObject() { var renderer = GetComponent(); float colorValue = Mathf.PingPong(Time.time * 0.5f, 1); renderer.material.color = new Color(colorValue, colorValue, 1.0f); // Change to a gradient color } }

Nice but you've created a cube with 24 vertices instead of 8. Faces can use the same vertices.

Great effect, if you were moving an actual jelly object around though, wouldn't it tip backwards when moving instead of forwards?

A few days ago, when i played red dead redemption, i was really impressed by the running and walking animation and asked myself how you could do this - so i think ive found it :D

[@arpitsrivstva]

it;s actually like that Plant vs Zombies plants if you have played that as well. BTw your playlists are awesome!

For Those who want a default size unity Cube (1, 1, 1) private Vector3[] GenerateVerts(){ return new Vector3[]{ // Bottom of Cube new Vector3(-0.5f, 0, 0.5f), new Vector3(0.5f, 0, 0.5f), new Vector3(0.5f, 0, -0.5f), new Vector3(-0.5f, 0, -0.5f), // Top of Cube new Vector3(-0.5f, 1, 0.5f), new Vector3(0.5f, 1, 0.5f), new Vector3(0.5f, 1, -0.5f), new Vector3(-0.5f, 1, -0.5f), // Left Side of Cube new Vector3(-0.5f, 0, 0.5f), new Vector3(-0.5f, 0, -0.5f), new Vector3(-0.5f, 1, 0.5f), new Vector3(-0.5f, 1, -0.5f), // Right Side of Cube new Vector3(0.5f, 0, 0.5f), new Vector3(0.5f, 0, -0.5f), new Vector3(0.5f, 1, 0.5f), new Vector3(0.5f, 1, -0.5f), // Front of Cube new Vector3(0.5f, 0, -0.5f), new Vector3(-0.5f, 0, -0.5f), new Vector3(0.5f, 1, -0.5f), new Vector3(-0.5f, 1, -0.5f), // Back of Cube new Vector3(-0.5f, 0, 0.5f), new Vector3(0.5f, 0, 0.5f), new Vector3(-0.5f, 1, 0.5f), new Vector3(0.5f, 1, 0.5f) }; } private int[] GenerateTriangles(){ return new int[]{ // Bottom 1, 0, 2, 2, 0, 3, // Top 4, 5, 6, 4, 6, 7, // left 9, 10, 11, 8, 10, 9, // right 12, 13, 15, 14, 12, 15, // front 16, 17, 19, 18, 16, 19, // back 20, 21, 23, 22, 20, 23 }; }

And I was wondering why my meshes had such a weird lightning effect. Thank you!

Can the next video be about putting a prefab/model into a fps so it moves his legs, arms and head with the movements of the FPS character

[@GeoGames_Dev]

SuperTG005 interesting yes :)

[@Wojbest_YT]

Is it just me or this music sounds straight out of a goofy roblox tycoon

[@GeoGames_Dev]

Good video as always
