static

Check if we can build the building.

Parameters

type	Unit that can build the building.
building	Building to be build.

Returns

True if made, false if can't be made.

Note

We must check if the dependencies are fulfilled.

AiCheckCosts()

static int AiCheckCosts ( const int *  costs )

static

Check if the costs are available for the AI.

Take reserve and already used resources into account.

Parameters

Costs for something.

Returns

A bit field of the missing costs.

AiCheckingWork()

static void AiCheckingWork ( )

static

Check what must be built / trained.

AiCheckRepair()

static void AiCheckRepair ( )

static

Check if there's a unit that should be repaired.

AiCheckSupply()

static int AiCheckSupply ( const PlayerAi &  pai, const CUnitType &  type  )

static

Check if the AI player needs food.

It counts buildings in progress and units in training queues.

Parameters

pai	AI player.
type	Unit-type that should be build.

Returns

True if enought, false otherwise.

Todo:

The number of food currently trained can be stored global for faster use.

AiCheckUnitTypeCosts()

static int AiCheckUnitTypeCosts ( const CUnitType &  type )

static

Check if the costs for an unit-type are available for the AI.

Take reserve and already used resources into account.

Parameters

type	Unit-type to check the costs for.

Returns

A bit field of the missing costs.

AiCollectResources()

static void AiCollectResources ( )

static

Assign workers to collect resources.

If we have a shortage of a resource, let many workers collecting this. If no shortage, split workers to all resources.
