how to avoid Random.Range() function keep producing the same number. This issue is found when adding the random walk functionality to the zombie, where the zombie just keep moving in the same direction rather hopping around.

side note: 

When

* the plane the gameobject is on is not flat

* none of the constraints of rigid body is ticked

* the game object uses a sphere collider or capsule collider

There is a high chance the game object would roll over due to the affect of gravity and uneven ground since it’s using a round collider (imagine a football)

the unity navigator api provides the path finding solution. I’ve used on the zombie to find a path to the player. It’s pretty powerful, has many parameters that you can control with. However the downside would be when you’ve got a large map, it would take quite a while to bake the NavMesh Map (and the generated baked NavMesh map is quite large in size as well, which is bad for collaboration).

solution to solve the issue when using imported unit asset store packages

[godiyuze]

Again, since player and zombie are both rigid body, the zombie’s position could never reaches the player’s position. Although I have already stopped update the NavMeshAgent’s destination when the zombie is close enough, the zombie would unavoidably push the player back a bit when it first reaches the player (due to the fact that its destination is set to the player’s position). 

The trick to solve this problem is to calculate the zombie’s heading and subtract a unit vector of that from the player’s position. So that the zombie’s position would just be somewhere near the player, rather than the central position of the player. 

here’s the code:
