Recently, a forum friend asked (in pm) why this PG (a freeCam mousewheel zoom)… that Arte and I had once built… quit working.
I fiddled around and I think I got it working again… with THIS pg.
Notice lines 25-38. WheelData used-to work, in some browsers, at some time. Then we needed detail for some browser(s). Now it appears that deltaY is the trend.
I know these mouseWheel properties are “W3C wobbly”, a bit. There seems to be cross-browser issues, and neg/poz issues, and any number of other issues.
So, speaking of cross-browser… I cannot get the #23 playground to load-into my IE. Error… something to do with scripts (playground app issue?). And so, I was not able to test this freecam mousewheel zoomer… in IE. And I don’t have any other browsers… for full testing.
Anyone want to address any of this? What’s wrong with IE load? What’s “the best” cross-browser way for us to do freeCam mousewheeler? Is #23 best… check for legacy stuff first, then get deltaY as a final attempt?
Line 44… is an issue, too. Some browsers’ wheel-props need < operator, some need > operator. Erf.
Should we make freeCam mousewheel-zoom… be an add-on “camera behavior” or maybe a modified camera.input for freeCams? Thoughts? (thx)
PS: Line 25 deltaMode defaults == 1. I set it to 0 for no reason at all, and I don’t know what it does… at all. SO, experimenters… you might wish to disable that line, or read about it.
