Programming Adventures 2 - Unity3D Translation

Programming Adventures 2 - Unity3D Translate When moving objects using gameObject.transform.translate(x,y,z), its direction is based on the object's local transformation.

That means that a square object rotated 90 degrees right will translate +Y when translated by (10, 0, 0).

This bug happens when trying to translate objects using world space vectors.

Solution The solution is to use gameObject.transform.SetPositionAndRotation( gameObject's position + translation direction, __); this avoids the local transformation stack!

var currentXTranslation = 0; $(document).ready(function () { $("#NavigateLeftButton").hide(); $("#NavigateLeftButton").click(function(evt) { currentXTranslation += 100; $(':root').css('--current-x-translation', currentXTranslation + "vw"); CS…
