Troubleshooting
That means you didn't copy this file to your app directory and it can't link it at runtime.
Your steam client should be running (or you can copy the steamclient dynamic library into your app directory).
Steam can't determine for which steam application you are trying to initialise the API. Either launch the game from Steam, or put the file steam_appid.txt containing the correct appID in your app folder. steam_appid.txt should contain just your application id, nothing else.
This indicated your Steam account is limited, missing some features of Steam. You need to do one of the following things to access all Steam features:
- Purchase a game for Steam store
- Redeem a Steam gift
- Complete a microtransaction
For more details, please refer to Steam support.
In order for the Steam Overlay (activated by "Shift + Tab" by default) to work properly, you need to have your Node-Webkit draw every frame. Normally, the browser won't redraw every frame when it's idle.
One possible solution to this would be, to insert a small 1x1 pixel canvas element, which you update in every frame. Example:
<html>
<head>
<script>
function forceRefresh() {
var canvas = document.getElementById("forceRefreshCanvas");
var ctx = canvas.getContext("2d");
ctx.clearRect(0, 0, canvas.width, canvas.height);
window.requestAnimationFrame(forceRefresh);
}
</script>
<body onload="forceRefresh();">
<canvas id="forceRefreshCanvas" width="1" height="1"></canvas>
</body>
</html>Now Node-Webkit will redraw every frame at the current refresh rate (in most cases 60 fps). This hack might not be necessary for game using WebGL because a canvas is probably already refreshed every frame for rendering.
If this doesn't seem to work, try adding the chromium flag "--in-process-gpu" to your package.json as well.
If the overlay appears strange, like other background windows are mixing with it try to remove the transparent flag in windows property of package json.
"window": {
"toolbar": false,
"fullscreen": true,
"frame": false,
//"transparent": true, // now should work correctly
"no-edit-menu" : true
},
