Combat service

Simulates a combat game where the endpoint has to return the next target to attack.

Solution

A service which accepts an input JSON on HTTP, with the info about the battlefield and returns the next coordinate to attack.

The next target depends on the protocols that are passed to the request, they should be compatible between them. For example, closest-enemies and furthest-enemies protocols aren't.

Available protocols:

• Prioritize closest enemy target 'closest-enemies'
• Prioritize furthest enemy target 'furthest-enemies'
• Prioritize allies targets 'assist-allies'
• Don't attack any target with allies 'avoid-crossfire'
• Attack a mech target. Otherwise attack another target 'prioritize-mech'
• Don't attack mech targets 'avoid-mech'

It has a REST api under /targets resource accessible.

REST API endpoints:

 POST /targets/radar
   Accept: application/json
   Content-Type: application/json
   {
     "protocols":["avoid-mech"],
     "scan":[{"coordinates":{"x":0,"y":40},"enemies":{"type":"soldier","number":10}}]
   }
