Control movement in FOLLOW PATH ANIMATION

Hi:

I created a path (path_azul)

I created another path (path_rojo)

(Is a copy of the first path)

I add a mesh (rojo)

I add another mesh (azul)

I parent mesh (rojo) to path (path_rojo) and select FOLLOW PATH.

I want the mesh (rojo) follow the path (path_rojo)

I parent mesh (azul) to path (path_azul) and select FOLLOW PATH.

I want the mesh (azul) follow the path (path_azul)

The mesh (rojo) and the mesh (azul) overlaps.

Mi questions are:

A)

How can I DELAY the beginning of mesh (azul) movement.

For example:

  • mesh (rojo) starts to move on frame 1

  • mesh (azul) starts to move on frame 10

B)

How can I STOP mesh (azul) movement.

I want mesh (azul) TO STOP in the middle of the path.

Thank you in advance.

I attach the blender file for further examination.

Select Curve object. Under Curve Object Data button you will find Path Animation Property. Activate it.

Total frame count need to match Time line frame count.

Evaluation Time sets the location of object along the path. It is in percent.

To Key frame animation, you need to set the time in Time Line Window. Slide the Evaluation Time to what you want. Hover mouse over Evaluation Time bar, then hit [I] to key frame it.

I parent mesh (azul) to path (path_azul) and select FOLLOW PATH.

Use a Follow Path constraint http://wiki.blender.org/index.php/Doc:2.6/Manual/Constraints/Relationship/Follow_Path
