Fighting for position

Ok. Weekend is over again.  I have not been able to get too much work done in Holocene this weekend as I had other things to do (and yesterday night I wasted my time watching The Marathon Man).

What I did do is making a start with moving units. For that, I made another of these primitive shapes based Workers. A capsule for the body, spheres for head and red nose to know which way he's facing and an elongated cube for arms. And a worker script and some needed Unity components.

First thing I set out to do is to implement the walking behaviour that I made for goats. When the unit is selected and the player rightclicks on the ground somewhere,  the unit is going there. Quite easy.

When clicking on a friendly unit, the unit should go there and stop right next to it.  Well, that gave us this little gif that I shared on Twitter:

Now what happens there? Note that I have not yet implemented any fighting mechanics.  These workers are not fighting per se, but yet they actually are. The thing is, the moving one is trying to stand on the spot where the stationary one is already standing. Because two entities can't occupy the same position, there's squeezing going on.

This was actually quite easy to fix. The worker script knows what object it's going to and that object knows its size. All we need to do is tell the walking behaviour script what the size of both objects is. Add them up and we have the stopping distance. 

This is actually really all I pulled off this weekend.  Hopefully I have more time for my game this week.
