This was build for a college project to visualize concurrency (using mutexes) on resources.
In order to visualize we created a world where people are trying to build a town.
The thing is, each person has its own thread.
- A* for pathfinding.
- Dijkstra's algorithm to find the closest job (ex. A lumberjack will look for the closest tree to cut).
- Mutex to lock resources (Ex. Tree, Building spot...).
- MonoGame Framework for the Graphical layer.
There are 3 types of NPCs : Buidlers, Carriers & Woodcutters.
- The
Buildersgo to a construction site to build. - The
Carriersgo get material from the town center to the construction sites needing it. - The
Woodcuttersgo chop down tree and bring it back to the town center.
Each Villager is a thread, so in order to avoid concurrency problems, we use mutex & semaphores.
When something happens (ex. Wood arrived to the town center, a tree is cut, etc...), this is sent to all Villagers and they can either ignore it, or do something about it, depending on their type.
-
Place objects using the mouse (as seen in the video)
- Using left click will place the currently selected object (shown at the top left of the screen)
- To change the object you press the corresponding keybind.
- (T) Trees
- (H) House construction sites
- (R) Rocks
- (W) Woodcutters
-
Show a NPC information
- You can also right click on a NPC to check his state
- what is his current state (ex. Walking)
- where is he going (position)
- what is his current task (ex. GoingToTree)
- You can also right click on a NPC to check his state
