Hi,
I started a small project combining the framebuffer picking example with an orbit camera.
See:
https://playcanvas.com/editor/scene/2162463
I was using the default orbit scripts from the asset library and the picker_framebuffer script from the example-project here:
https://playcanvas.com/project/405856
Using it in this form resulted in an incorrect hit detection, after taking a look into the code and the picker documentation:
I changed following line in the picker_framebuffer.js code, which resulted in (probably) correct functionality.
var selected = picker.getSelection(
Math.floor(event.x * (picker.width / canvasWidth)),
// original code -> wrong?
//picker.height - Math.floor(event.y * (picker.height / canvasHeight))
// my changed code -> correct?
Math.floor(event.y * (picker.height / canvasHeight))
);
Had there been an api change (assuming as the old code seems to mimic a y coordinate from bottom) ?
If so, maybe the tutorial and/or example file should be updated as well.
Thanks for any heads up,
