Description

Measures the distance between two nodes in a scene.

The default behavior (no flags used) returns the distance at the current frame. The -avg, -min, -max, -range, and -sd flags all return a value that's based on a number of frames. That number of frames is the play range by default unless the -rangesOnly option is used.

Name	Argument type	Exclusive to	Comments
`-avg`	—	-min, -max, -range, -sd	Returns the average distance
`-min`	—	-avg, -max, -range, -sd	Returns the minimum distance
`-max`	—	-avg, -min, -range, -sd	Returns the maximum distance
`-range`	—	-avg, -min, -max, -sd	Returns the difference of the min and max
`-sd`	—	-avg, -min, -max, -range	Returns the standard deviation
`-rangesOnly`	—	—	Computes distance calculations over the selected time ranges only
`-mustHaveKeys`	—	—	Only computes distance on frames where both nodes have a key present

Return value

float

Returns the distance in mm from node1 to node2

Examples

// create a clip
create Clip Clip_1;
 
// create two objects which we want to compute distances between 
create Marker Marker_1;
create Bone Bone_1;
 
// move the bone 300 and 400 in x, y (respectively
setKey "Translation.X" 300 -onMod Bone_1;
setKey "Translation.Y" 400 -onMod Bone_1;
 
// show that the bone is 500 mm away from the marker as expected
print(getDistance("Marker_1", "Bone_1"));
