Function Documentation

static int AiCheckSurrounding	(	const CUnit *	worker,
		const CUnitType *	type,
		int	x,
		int	y,
		bool &	backupok
	)			[static]

Check if the surrounding are free. Depending on the value of flag, it will check : 0: the building will not block any way 1: all surrounding is free

Parameters:

	worker	Worker to build.
	type	Type of building.
	x	X map tile position for the building.
	y	Y map tile position for the building.
	backupok	Location can be used as a backup

Returns:

True if the surrounding is free, false otherwise.

Note:

Can be faster written.

	)

< Find nice building place

Find free building place.

Parameters:

	worker	Worker to build building.
	type	Type of building.
	dx	Pointer for X position returned.
	dy	Pointer for Y position returned.

Returns:

True if place found, false if no found.

Todo:

Better and faster way to find building place of oil platforms Special routines for special buildings.
