FindPartsInRegion3WithIgnoreList
This item is deprecated. Do not use it for new work.
For thread safety, this property is not safe to read in an unsynchronized thread.
Returns an array of BasePart
s in the given DataType/Region3
that aren’t in, or a descendant of an entry in, the given IgnoreList.
This function takes an optional maxParts parameter (default 20) which limits the number of BasePart
s that can be returned. Once this number has been reached, the search for BasePart
s will stop. This means some BasePart
s may not be returned even if they are within the DataType/Region3
If no BasePart
s are found, an empty array will be returned.
This function is a variant of Workspace/FindPartsInRegion3
with the addition of an ignore list. This allows the developer to exclude certain BasePart
s or Model
s, for example characters, from the search. Those looking to find BasePart
s in a Region3 using a white list, should use Workspace/FindPartsInRegion3WithWhitelist
.
How do Region3 checks work?
Checking if a part overlaps a DataType/Region3
is not a simple process. It actually is time consuming and complicated. Instead it checks if parts are roughly in the same area. When this function is called, it figures out which voxels contain the DataType/Region3
. It then figures out which parts might be in those voxels. It does this by comparing the axis-aligned bounding box (sometimes called the AABB) of the part with the voxels. The axis-aligned bounding box can be seen in Roblox Studio when a part is selected.
This means that the area that is inspected by the function may be larger than the DataType/Region3
. For this reason it is recommended to make sure that the DataType/Region3
is on the voxel grid. The best way to do this is by setting the coordinates of the DataType/Region3
to multiples of 4 (since voxels are 4 x 4 x 4 studs).
This method is a fairly quick and easy way to see if parts are in a general area. If a game needs to know if parts are exactly in an area, then BasePart/GetTouchingParts
should be used. There is a higher cost to using BasePart/GetTouchingParts
since a part is needed in the Workspace
and the function takes more time to run.
Notes
- If a nil value is given in the ignore list, instances after this value will not be ignored
