Once support for optional win conditions (see #17) is merged via #34, we can start building on top of the feature by adding a win condition to reach multiple optional conditions. This is fun because we can set up optional conditions like:

• Defeat unit by label
• Capture 5 buildings
• Escort 1 unit

And then define a win condition that requires reaching three optional conditions to win the game. Together with secret conditions, this opens up exciting possibilities for map scenarios where you might have to discover hidden optional conditions to win the game.

Code & Steps

This task is about implementing a new win criteria and condition called "OptionalConditionAmount" which should have a players and amount field (next to the default fields like reward and hidden). I believe that based on #34, this condition should also be possible to be optional, even though that might be slightly confusing when used.

• WinConditions.tsx for data structures and where to add a new win condition. Check out other win conditions that have an "amount" field. Ideally the validation for this win condition should verify that the number of optional conditions defined for the map is higher or equal to the "amount" specified on the win condition. For that validateWinCondition should be changed to take the number of win conditions of the map.
• checkWinCondition.tsx for checking whether a condition was meet. checkWinCondition should look for an ActionResponse of type OptionalCondition and then go through all win conditions to check if the player or any player within the team completed enough win conditions.
• PlayerCard to show how many optional conditions were reached by the team compared to the amount, similar to the other conditions that are shown there. Feel free to pick an icon from https://icones.js.org/collection/pixelarticons or otherwise use a placeholder and I'll make a fitting one.
• Please add a test to verify the win condition works as expected.

TypeScript via pnpm tsc should guide you through adding various pieces of code once you add the win condition.

Note: This win condition should be triggered if enough optional conditions are fulfilled by the player or anyone on the same team. Therefore the check in checkWinCondition should look for each condition's completed set and check if the player id match the same team as the player who unlocked the optional condition via map.matchesTeam(actionResponse.toPlayer, completedPlayerID)
