Probably of topic, BUT I need help implementing a radar.

[ricard2798]

So here is my situation. even though my game for the VR JAm does not really need a radar, i could REALLY use one to make it better. Unfortunately, the 2 attempts i have gone through have not worked too well. i am using unity 5. the first one was to use a script from an asset called Airstrike. unfortunately it does not render correctly (if at all). i only see the radar in the editor game window when I pause the running app (which basically turns the screen all black with the radar skin on it). So after trying for a day, i gave up.

Then I tried a tutorial from a person in youtube (https://www.youtube.com/watch?v=O8is_EikILA).. and that one worked, but all my radar objects would render BLACK (so no colors). So if anyone can help me out (either sell me a working on gear vr prefab, teach me, etc) i would appreciate it. i would even pay a small fee if needed.

please let me know. All i need is a simple radar to track enemies. Tracking other objects is a plus, but not a necessity. keep in mind, i am a noob, going at it solo, can't code and ma just hacking my way as a I can for the Jam 🙂

Have you tried a render texture?
http://docs.unity3d.com/Manual/class-RenderTexture.html

Place camera up high in orthographic mode and attach a small plane in front of the gear vr camera which the overhead camera renders to.

Then you add radar objects on a different layer and make the overhead camera culling to only show radar objects to avoid rendering the whole scene.

I think that is what I did based on tutorial 2, but all my radar objects rendered dark black... in preview mode they would show full color and all, but the moment I played the scene, they went black.. fully eorking, but all items were black

it's probably a texture bug in unity5/android try a different shader
if you're using diffuse colour to colour the dots try an unlit texture instead etc.
if all else fails you can use symbols instead like square and triangles to differentiate them.

hey spinal. i first want to thank you for trying to help me figure this out. It was a great help, and your ideas were solid.

Anyways, i finally got it working. The problem with what i has attempting is that i had an extra camera which I was rendering to another layer, and that was not working correctly. it took me a few days in the backburner to figure out, that perhaps I should have that camera, not render into the other cameras, but instead as a render texture into an object (plane, box, etc), and then place that object parented to the camera rig 🙂

Well, it worked perfectly... thanks for helping this noob, i appreciate it 🙂
