A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games.

How can I make an object follow a fixed path (track)? but...

3 posts in this topic

The vehicle called the VNA will follow a fixed path which is the aisle between the rackings.

But at some point, the VNA will be able to stop at each bay. What is the best way to move this object?

Waypoints, or weighed A* (don't know what that's called), but something like the path within the straight line

will be given the highest score.

I am not sure what is your problem.

If you want to move object to specific location:

1. (opt) rotate it to face target location


targetLocation = Path[currNodeInx].node_pos
objectPos += (targetLocation - objectPos).normalize() * moveSpeed

3. test if reached destination and increment path index:

minimumDist = 0.1 // minimum dist to target to consider it has reached its current destination
minimumDistSq = minimumDist*minimumDist // squared
if((targetLocation - objectPos).lengthSq() < minimumDistSq)
    currNodeInx++ // or decrement if you want to go back, or wrap around so it will loop thru the path

4. you can add something like weight to Path to modify moveSpeed so object will move slower/faster

targetLocation = Path[currNodeInx].node_pos
objectPos += (targetLocation - objectPos).normalize() * moveSpeed * Path[currNodeInx].weight
