Description
- Description:
- Searches for an empty position around specified position. The search starts looking for an empty position at a minimum distance of [radius] from the [center] and looks as far away as [radius + maxDistance].
- If a vehicleType parameter is specified, the search will look for an empty positions that is big enough to hold that vehicle type.
- If an empty position isn't found, an empty array is returned.
- Groups:
- Positions
Syntax
- Syntax:
- center findEmptyPosition [radius, maxDistance, vehicleType]
- Parameters:
- center: Array - search area center position in format [x,y] or [x,y,z] in which case z is ignored. Accepts Position2D or Position3D
- radius: Number - start searching no closer than radius from the center
- maxDistance: Number - stop searching no further than radius + maxDistance from the center
- vehicleType: String - (Optional) class name of a vehicle to accommodate
- Return Value:
- Array - a suitable empty position in format Position3D or [] if not found
Examples
- Example 1:
- Example 2:
- Example 3:
- Check if exact position is empty:

- Keep search radius short and sweet, under 50 metres maybe. Searching big area takes long time and will result in your game stop responding until the search is over. isFlatEmpty is probably more suitable for a larger area search.

- I think the radius parameter should be treated as a 'minimum distance' from the centre position. I found that the parameter name radius was not very clear. Also, if radius is greater than max distance then the function will always return an empty array. Here is an snippet of code I use to find a safe landing zone for an extraction helicopter. It may be useful for someone. In the above example, make sure that "_max_distance" is greater than 30, otherwise the while loop will go forever.
