Returns an array of
BaseParts 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
BaseParts that can be returned. Once this number has been reached, the search for
BaseParts will stop. This means some
BaseParts may not be returned even if they are within the
BaseParts 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
Models, for example characters, from the search. Those looking to find
BaseParts in a Region3 using a white list, should use
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.
