Input.GetMouseButtonDown not working on WebGL build

Questions & Answers
1

I have a project for a client which specifies for a WebGL build to be supplied, but the game breaks as the build does not seem to support the detection of any mouse presses using the Input class, although it does recognise mouse clicks on UI Canvas elements.

I have tried unchecking the ‘strip engine code’ option in the player settings but that has made no difference.

I am at a loss to know how to debug WebGL but I’m interested to know if anybody could suggest a solution or workaround. I am on Unity 5.5.1p3 on Mac. Thank you.

I figured out what the issue was. I was using Input.touchSupported to check whether I should be attempting to use touch or mouse input, and this always returns true on any WebGL build, presumably because the build can’t tell what actual hardware is attached, even though I was on a laptop with a mouse.

you can use Input.GetKeyDown(KeyCode.mouse0); instead.
