Overview

There's a demo Altspace world here: https://account.altvr.com/worlds/1046572460192825569/spaces/1183034043432698356

Usage

Built-in Content

You can configure the app to load different sets of data to load by specifying the "kit" parameter. For example:

wss://mres.altvr.com/helmets?kit=city_helmets

Here are the built-in sets of helmets:

• "city_helmets"
• "space_helmets"
• "galaxy_flyin_3"
• "star_wars_scout_helmet"
• "samurai_helmets"
• "town_helmets"
• "viking_helmets"

If you don't pass a "kit" parameter, it will load all of the built-in ones together.

Controls

These are the controls that appear at the end of the list. Users attach an object to themselves by clicking on the preview object. The preview object has an invisible cube.

• (click on an item) - attach
• X Button - unattach
• +/- Buttons - scale up/down
• Up/Down Arrows - move up/down
• Forward/Back Arrows - move forward/back

By default, you will see all controls. Pass "controls=min" to hide all except the "unattach" button.

wss://mres.altvr.com/helmets?controls=min

Pass "controls=none" to hide all buttons (WARNING: users will not be able to unattach items).

wss://mres.altvr.com/helmets?controls=none

Content Packs

Alternatively, you can use the Content Pack feature by creating one on altvr.com and passing a "content_pack" parameter:

wss://mres.altvr.com/helmets?content_pack=1187493048011980938

This allows you to customize your own set of helmets from one or more Altspace World-Building Kits. The JSON field should contain a top-level key for each helmet with a "resourceId", usually an Artifact ID. That is the only required field. You can find these by browsing through your Kit's artifacts. Example:mµ

{
    "businessman": {
        "resourceId": "artifact:1167890491962818802"
    },
    "businesswoman": {
        "resourceId": "artifact:1167890476561334511"
    },
    "femalecoat": {
        "resourceId": "artifact:1167890502222086388"
    }
}

See more examples in the public/data folder.

Options

You can optionally set "position" / "rotation" / "scale" to adjust the helmet when it attaches. You can also set "menuPosition" / "menuRotation" / "menuScale" to adjust the helmet in the menu. Both rotations default to (0,180,0). Set "attachPoint" to change where the object attaches to your avatar skeleton (default is "head"). You can find a full list of attach points here: https://microsoft.github.io/mixed-reality-extension-sdk/index.html#attachpoint

{
    "spacehelmetship": {
        "resourceId": "artifact:1166530075533771277",
        "position": {
            "x": 0,
            "y": -0.48,
            "z": 0
        },
        "rotation": {
            "x": 0,
            "y": 0,
            "z": 0
        },
        "scale": {
            "x": 7.5,
            "y": 7.5,
            "z": 7.5
        },
        "menuPosition": {
            "x": 0,
            "y": -0.1,
            "z": 0
        },
        "menuRotation": {
            "x": 0,
            "y": 0,
            "z": 0
        },
        "menuScale": {
            "x": 1.5,
            "y": 1.5,
            "z": 1.5
        },
        "attachPoint": "spine-middle"
    }
}

You can also adjust the spacing between each preview object. The default is 1.5 meters:

{
    "spacehelmetship": {
        "resourceId": "artifact:1166530075533771277"
    },
    "options": {
        "previewMargin": 10
    }
}

The order doesn't matter for where you put the "options" entry.

FAQ

• Why doesn't my attachPoint work? Some attachpoints may not be supported by Altspace or just bugged. For example, finger ones like "right-pinky" and "right-middle" do not seem to be working right now. The workaround is to attach somewhere close like "right-hand" and move + rotate from there.
