# Diagonal Movement
|
|
To disable diagonal movement you need to configure the finder. The finder takes
|
|
a configuration object with an option called `diagonalMovement`. Setting this
|
|
option to `DiagonalMovement.Never` will disable diagonal movement completely.
|
|
Let us try it.
|
|
|
|
```javascript
|
|
var finder = new PF.AStarFinder({
|
|
diagonalMovement: PF.DiagonalMovement.Never
|
|
});
|
|
```
|
|
|
|
See that the path is straight now:
|
|
|
|
|
|
|
|
The `diagonalMovement` option can take any of the following values:
|
|
|
|
* Always
|
|
* Never
|
|
* IfAtMostOneObstacle
|
|
* OnlyWhenNoObstacles
|
|
|
|
To understand them consider the following four simple maps labelled A, B, C and
|
|
D. A has no obstacles for diagonal movement from green to orange cell, B and C
|
|
have one obstacle and D has two obstacles.
|
|
|
|
|
|
|
|
## Always
|
|
With this option PathFinding.js will always find a diagonal path, irrespective
|
|
of the obstacles when moving diagonally.
|
|
|
|
|
|
|
|
## Never
|
|
With this option PathFinding.js will only find straight paths and will never
|
|
find any diagonal paths.
|
|
|
|
|
|
|
|
## IfAtMostOneObstacle
|
|
With this option PathFinding.js will find diagonal paths only if there is at
|
|
most one obstacle for the diagonal path.
|
|
|
|
|
|
|
|
## OnlyWhenNoObstacles
|
|
With this option PathFinding.js will find diagonal paths only if there are no
|
|
obstacles for the diagonal path.
