As a result, the camera is forever rotating around the ball, rotating on it's own y axis. Problem is, the marble is constantly rolling so it's forward vector changes with every frame. It uses the marble's forward vector, without the y and then places itself behind the marble. So why does the slow moving ball not stop for 10 to 20 seconds?Īlso, the camera is all wierd using this script. Because it moves up the slope I assume my force is immence. Slowly like ever, but forward non the less, for about 10 to 20 seconds, then it changes direction and comes back, ever so slowly still, before moving up the slope still ever so slowly. Forward speed is calculated by using the 'vertical' keys, yet when the ball gets to the end of the slope, I press the backwards movement key and the ball just keeps going.

The one where the guy builds the level with his son and then scripts the movement for the marble. :?: And lastly, for movement I use the script from the tutorial.

How do i create more lifelike physics here? At the moment, when it reaches the slope, it goes down the slope without the need for me to press any buttons, but the speed of the marble stays constant throughout. When I set the ball in motion, I want it to move forward at the speed at which it is being pushed, then when it reaches the slope, it should start rolling down and gain speed/velocity/momentum/whatever. I simply decided to build this game to test the physics engine and so far it doesn't seem to do what I expect. Lastly, and more importantly, my ball doesn't behave like I would have expected it to. The method I use to stop this from happening is to increase the mass, but then the force is not strong enough to move the marble except at crawling speed. It should not be able to move up the slope at all. If I make the force strong enough to actually move the ball at a reasonably fast speed, then the force is so strong that when I hold down the backwards movement key, it goes up the slope for the level. :?: The second one is the relationship between force and mass. To solve this I changed the gravity field to 30. When I place it in the game and place it above the track, it falls down VERY slowly indeed, no matter how much mass it has. The PC is a simple sphere created using Unity. The levels would be something like i-Ninja with various obstacles to overcome except the PC should never be able to actually roll backwards except on a flat surface and the PC should never be able to move up a slope. Your controll over the PC (player character) is simply left and right force additions for direction changing and forward and backward for speed adjustments. The game I want to make is almost like the rolling levels on i-Ninja on Xbox (or Sonic 2 on the Genesis) where you are a ball rolling through a track, sometimes at breakneck speeds. Please allow me to post my problems and please see if you can help me out. I am new to Unity and trying to make a real simple game that relies almost exclusively on the physics engine and have found that the physics engine is without my understanding.
