<AR GAME> Oxygen Poor

Development and design 2




Set up interactive marine ecology in AR

 

Part 1 --- AR Foundation Plane Tracking


  • Learning Reference

- Track a specific flat area

- Run AR program after 'Project setting'

- Learned the role and usage of prefabs in unity

Tutorial

- AR Foundation Plane Tracking

- AR Foundation Plane Tracking - Hiding Tracked Planes

  • Steps

- First, install the AR plugin---- AR Foundation，AR Kit.

- Add AR Session Origin, AR Session,

Change the label of AR Camera to MainCamera.

- Add Component: AR Plane Manager - Delection Mode.

I choose to only detect the horizontal plane.


  • Debug

- Need to change Package name, Camera Usage Description, Artichitecture (ARM64) in Player Setting.

















Part 2 --- Changing Plane Material


  • Learning Reference

- Learn to replace Material in Mesh Render, so that the generated plane has the

effect of seabed sand.

Tutorial

- ARFoundation Changing Plane Material

  • Steps

First find the Mesh Collider in the AR Default Plane, and add the sand texture material I found myself to Materials.


  • Test



Part 3 --- Multiple Object Placement


  • Learning Reference

- Learn how to generate multiple models on the tested plane by tapping the

screen.

- Create a script, and then call the spawn object.

- Adjust the position and size of the model.

Tutorial

- AR Foundation Object Placement

- AR Foundation Multiple Object Placement

  • Steps

- Make 5 water plant models and adjust the size of the models.

- Turn the model into a prefab and compare the scale of the model.

- Add a material shader to the water plant model.

- Create spawn object script.

- Multiple model placement + UI button.


I tried to connect the nodes by myself and made a dynamic shader with aquatic plants swaying, but the dynamic effect was not good.








So I chose to adjust the shader parameters of the existing material.












I made five models as prefabs and placed them in the AR environment to simulate marine ecology.


Create a spawnobject script and set Max Prefab Spawn Count and Placeable Prefab in unity.


I encountered a problem during the test and the model could not be placed on a horizontal surface correctly. So I put the model back into the maya file and re-modified the coordinate origin and size of the model.


  • Test

The test result was successful !
