running lighting example

[joeblew99]

the light example it dependent on your server.

func fetchAssets(gameEngine engine.Engine, complete func()) {
    os.Mkdir("TestAssets", 0777)
    patcher := client.NewClient("TestAssets", "http://walesey.net")
    done := make(chan bool)
    go func() {
        patcher.SyncFiles("TestFiles")
        done <- true
    }()

It just downlods the large texture files so i dont need to check them in to source control. You can safely remove this if you have your own assets.

[joeblew99]

Am trying to get up to speed for how to do that :)

I have a "TestAssets" directory. I think it might have been generated ? Then trying to work out how to get the example to mount it as it were to get a full end to end example going. Getting that far would really help..

[walesey]

Correct, the TestAssets directory is generated. When you run this particular example the code attempts to download the required game assets into TestAssets. These are the files you should be receiving http://walesey.net/files

If you could give more detail that would help: 1) What files do you see in the TestAssets directory? 2) What behaviour are you seeing on the screen? 3) What console error do you get, if any?

Ok thanks for that it helps.

I got it semi working more now.... Here is what i do:

1. make it
2. run the editor for kicks. Its not usable yet it seems. But its not crashing.
3. Have a go at running the example/lighting. I am now getting some assets.

x-MacBook-Pro:go-engine apple$ make

./sBuilder shaders/basic.glsl vert > shaders/build/basic.vert

Using assetDir:  .

cd example/lighting

The behaviour is that i see the skymap (golden) and some fires burning in the background.

Heres the file listing... x-MacBook-Pro:go-engine apple$ cd TestAssets/ x-MacBook-Pro:TestAssets apple$ tree . ├── Fire.png ├── Spark.png ├── cloudSky.jpg └── wellScene ├── bricks │   ├── harshbricks-ao2.png │   ├── harshbricks-metalness.png │   └── harshbricks-normal.png └── frame1.mtl

Some files are missing, Might be an issue with the file sync: ~/go/src/github.com/walesey/go-engine/TestAssets $ tree . ├── Fire.png ├── Spark.png ├── cloudSky.jpg └── wellScene ├── bricks │   ├── harshbricks-albedo.png │   ├── harshbricks-ao2.png │   ├── harshbricks-glow.png │   ├── harshbricks-metalness.png │   ├── harshbricks-normal.png │   └── harshbricks-roughness.png ├── floor.mtl ├── floor.obj ├── frame1.mtl ├── frame1.obj ├── frame2.mtl ├── frame2.obj ├── ground │   ├── pineneedles-albedo.png │   ├── pineneedles-ao.png │   ├── pineneedles-glow.png │   ├── pineneedles-metalness.png │   ├── pineneedles-normal4.png │   └── pineneedles-roughness.png ├── metal │   ├── greasy-metal-pan1-albedo.png │   ├── greasy-metal-pan1-ao.png │   ├── greasy-metal-pan1-glow.png │   ├── greasy-metal-pan1-metal.png │   ├── greasy-metal-pan1-normal.png │   └── greasy-metal-pan1-roughness.png ├── torches.mtl ├── torches.obj ├── well.mtl ├── well.obj └── wood ├── plywood-albedo2b.png ├── plywood-ao.png ├── plywood-glow.png ├── plywood-metalness.png ├── plywood-normal1.png └── plywood-rough.png

Try running this command manually to download the Test files:

~/go/src/github.com/walesey/go-engine $ go get github.com/walesey/go-fileserver
~/go/src/github.com/walesey/go-engine $ go-fileserver -host walesey.net -path TestFiles -out TestAssets

thanks. it worked. Boy its slow though...
