Unity Webgl project program adaptive window settings
1. Unity Edior
Set the UI Scale Mode of the Canvas Scaler component of Canvas to Scale With Screen Size in the unity Editor.
2. Modify the published Index.html file
This method requires the use of jQuery, so jquery is called in the head part. As shown below
Then add the resizeCanvas method in the code block, use the method in jQuery to obtain innerWidth and innerHeight, and assign them to canvas. It should be noted that the format of canvas.style.width and height is a string ending in px.
function resizeCanvas(){
ar width1=$(window).get(0).innerWidth;
var height1 = $(window).get(0).innerHeight;
canvas.style.width = width1+ "px";
canvas.style.height = height1 + "px";
};
Called when the window size changes
$(window).resize(resizeCanvas);
In this way, when we change the size of the browser window, the Canvas in Unity will also change accordingly.
But we still need to call the resize function once when unity is loaded.
