◆ move_unit_along_route()

std::size_t events::mouse_handler::move_unit_along_route	(	const std::vector< map_location > &	steps,
		bool &	interrupted
	)

Moves a unit across the board for a player.

This is specifically for movement at the time it is initiated by a player, whether via a mouse click or executing whiteboard actions. Continued moves (including goto execution) can bypass this and call actions::move_unit() directly. This function call may include time for an animation, so make sure the provided route will remain unchanged (the caller should probably make a local copy).

Parameters

[in]	steps	The route to be traveled. The unit to be moved is at the beginning of this route.
[out]	interrupted	This is set to true if information was uncovered that warrants interrupting a chain of actions (and set to false otherwise).

Returns: The number of hexes entered. This can safely be used as an index into steps to get the location where movement ended, provided steps is not empty (the return value is guaranteed to be less than steps.size() ).
