View Full Version : Controlling an object along a spline Path?

11-21-2005, 02:38 PM
Im creating a city scene in which my camera will 'cruise' the streets. I decided to use a spline path with my camera CurveConstraint to it.

I want to be able to make the camera stop and the stop signs, but currently, with the setup, i cant figure out how to adjust the cameras motion to stop. Below is the image of just the camera and spline path. The red boxes are the stop signs. Id appreciate any help. Thanks

You can use the graph editor to slow and stop it once you get your spline layed out and the camera moving. You can use this method to control the motion, including easing in and easing out (like a car slowing and stopping then slowly accelerating). You can accomplish that with the tension setting.

Hope that helps.

I havent fully attempted the graph editor, but i think i looked at that in the beginning, ..my concern is that since im using a camera that is constrained to a splne path, there are no keyframes associated to the cameras motion, so i dont think ill have any control point within the graph editor.... does that make any sense or was i too confusing?

Maybe im not looking in the right area, but i tried the graph editor again, and my camera is showing no controls on the graph (which makes sense since the camera is constrained to a curve over time, which requires the camera to sit a zero to be accurately constrained).

This means that once I move the camera, The rest of the camera's motion around the curve is affected.

I would export the splines in modeler as a motion path so you do have keyframes to edit :)
