4. Create two more spheres, scaled down to ( 0.4, 0.07, 0.4 ). Position
these on the pole to act as mount points for the interactive cloth. The cloth
will attach at these points to the pole. Disable their mesh renderer so that you
cannot see them once they are placed correctly (overlapping the interactive
cloth). Make sure that these two spheres have a rigid body component so
that they can anchor the interactive cloth properly.
5. Create a new, empty GameObject , and name it MissionMgr . Attach the
MissionMgr script to this object. We purposely detach this script from the
player because the lifespan of MissionMgr may differ from the player ob-
ject.
Now that we have added our flag geometry, let's create some interactive objects to
collect and interact with. As there are 50 states, let's start with Alabama and repeat
the following steps for every other state, modifying the textures and state names as
appropriate:
1. Create a sphere and place it on the ground plane. Name it Flag-
pole_Alabama , and disable the mesh renderer component. On the sphere
collider, check the IsTrigger checkbox so that we can detect when the player
enters the object.
2. Add a CustomGameObject script to this object. Set the display name to
Alabama and the object type to flag .
3. Add a mission token script to this object. Set id=501 , title to token , and the
description to mission 1 token .
