Object appears to glitch as it moves whenever the camera follows it.
Okay so this Question will seem a bit to big tackle, but I figured I'd ask for some help anyway.
So I am making a simple kart racing, and right now I'm I've got a good set on the physics of the car. Instead of using real physics, It relies on raycasting to influence its' movement simply as follows.
" By firing a raycast down from each corner of the vehicle a certain distance (hoverheight), and if it detects a hit, it adds an upward force."
It took a bit of brain work, but I think it I got the cars' controller script to work properly. The real problem is when it interacts with the camera.Now for the camera, I used a script I made based on this smooth follow script that I found on the UnifyCommunity website.
now, when the camera views the player without the script, the player acts normally; smooth movement, no problems. However when the camera as the script, and when you move the player in game mode, that's when things get a bit problematic. As the camera views the player move around, the player glitches a bit. Not enough to break the game of course, though just enough for it to be noticed.
If anyone has any ideas, questions, or suggestions, be sure to reply or comment back on the matter. Just be sure to do some research and think over the question thoroughly. The coding for the scripts I'm using will be provided in this question for you to look over, in case you like to test out this scenerio for yourself. I'll also provide a link to the tutorial I used for making my character script, If your interested in making your own simple Kart racer. Think of said tutorial as a basis for more your own gameplay mechanics. Again, your words and support are well appreciated.
Thank you
