Smart Spikes

Directed Spikes is the second upgrade of the third path for the Spike Factory, it allows the Spike Factory to have target piorities.

Priorities

 * Normal: Places spikes like a normal Spike Factory.
 * Close: Places spikes at the track part nearest to the Spike Factory.
 * Far: Places the spikes on the track part the least close to the spike factory
 * Smart: Puts the spikes in the best position, but this Priority is bugged and instead places the spikes in the worst position
