Project 2 by Win Zaw

The final product in all it’s glory. For this project, there were a couple of hurdles that i’ve had to overcome. Firstly, i’ve had to create the 3d assets using a 3d software (maya). After I was done creating the 3d models and textures, i’ve had to create a terrain.

Firstly, i created a terrain model in unity and sculpted the terrain. I made sure that the edges of the terrain remained untouched as i wanted to create an infinite terrain script. If the terrain was even a little elevated, the end result would be an obvious seam.  I’ve also made an attempt to sculpt the terrain manually in Mudbox using a displacement mapping. This worked to a certain limit. However, as the process of converting object to terrain is time consuming, i’ve decided against it.

 

Once i was done with sculpting the terrain, i created a base texture, which would be the grass. I would then add another layer, which would be the soil. I would vary the texture to create a sense of erosion. Afterwards, i would create a grass texture and add in the trees using a paint function. The idea would be to create a dense forest in one area.

Afterwards, i created a couple of pillars and added an audio source to each of them. I initially had trouble adjusting the spread and minimum distance, but after much troubleshooting, i found out that the problem was from multiple audio listeners. I kept it to one and found that the audio now softened with distance.

I added a few ambient tracks from my recordings in Labrador Park. One was of the forests, one was at the docks, one was the sound of winds blowing and another one was a track from Radiohead callled “Bloom”. I chose that song as it inspired me to design the look of the project. In order to have the audio elements loop, i went to Premiere pro, cut off the front end of the audio and stuck it at the back, then i softened the front half and add the cut off section to blend in.

In creating this environment, i hope to make people immersed in the spaces of Labrador park. In future, i might also consider adding even more audio sources to more correctly. However, as a lot of the time had been spent on research and development, I’ve had little time to collect more audio samples and blend them in.

I added the infinite terrain script in C# (see below)

I also added an FPS camera and adjusted the movement parameters. (eg. Jump, mouse sensitivity, running speed and walking speed.)

  1. public enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 }
  2. public RotationAxes axes = RotationAxes.MouseXAndY;
  3. public float sensitivityX = 15F;
  4. public float sensitivityY = 15F;
  6. public float minimumX = -360F;
  7. public float maximumX = 360F;
  9. public float minimumY = -60F;
  10. public float maximumY = 60F;
  12. float rotationY = 0F;
  14. void Update ()
  15. {
  16. if (axes == RotationAxes.MouseXAndY)
  17. {
  18. float rotationX = transform.localEulerAngles.y + Input.GetAxis("Mouse X") * sensitivityX;
  20. rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
  21. rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);
  23. transform.localEulerAngles = new Vector3(-rotationY, rotationX, 0);
  24. }
  25. else if (axes == RotationAxes.MouseX)
  26. {
  27. transform.Rotate(0, Input.GetAxis("Mouse X") * sensitivityX, 0);
  28. }
  29. else
  30. {
  31. rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
  32. rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);
  34. transform.localEulerAngles = new Vector3(-rotationY, transform.localEulerAngles.y, 0);
  35. }
  36. }
  38. void Start ()
  39. {
  40. // Make the rigid body not change rotation
  41. if (rigidbody)
  42. rigidbody.freezeRotation = true;
  43. }

I also added in a global fog to create a fading effect, so objects in the distance would blend in with the skies. As for the skies itself, i added a default unity skybox.
