Detect mouse click location within canvas

由 笑着哭i 提交于 2019-12-07 15:16:37
问题 I'm having a real issue trying to define a function for where I click on empty space. So far I have managed to define where I click on an object - of which there are 10 - but now I need a separate function for when I am not clicking on any of the objects. The general idea can be found at http://deciballs.co.uk/experience.html. The objects are the rings. My code is below... Any ideas? var shapeObj = function (context, canvas, settingsBox, radius) { this.ctx = context; this.canvas = canvas;

If the user clicks 1 first and then clicks then 2, 2 runs off of some of the variables from 1. But I need 2 to be able to operate independently if 2 is clicked first. Therefore, I need some way in the 2 code to ask if 1 button has been clicked. Both 1 and 2 are public subs. I think there is something that I am missing with the
