WorldViz User Forum - View Single Post - Eliminate Sideways Motion when colliding w/Objects

Just though of another way to stop sideways motion. Check every frame if the view has moved in any direction other than forward or back.

Code:

#sudo code

#every frame
displacementVector = currentViewPosVector - lastViewPosVector
headingDisplacementVector  = vizmat.LookToQuat(displacementVector))
viewDisplacementHeadingDiff = vizmat.QuatDiff(headingDisplacementVector, viz.MainView.getQuat())
if viewDisplacementHeadingDiff != 0 or viewDisplacementHeadingDiff != 180:
    viz.MainView.setPosition(lastViewPos) #stop
