Direction¶
Description¶
The Direction Node is used to convert the typical four directional movement
input into a single value representing the primary direction of movement. This
is useful for things like switching sprite animation on
Objects to show the correct
animation for the movement. If the input suggests a diagonal movement, the
output will be a single value representing the "dominant" axis as defined by
the Vertical Priority parameter, if this is checked, then up/down will be
chosen over left/right if diagonal movement is indicated, if it is not checked,
left/right will get priority.
Note: unlike other nodes with port/parameter pairs, in this node the direction rows are not port or parameter, both are required. The port is the input, usually from a Controller node, while the parameter represents the output value that will be used if that direction is determined to be the dominant direction. In the example here, if only the right controller is non-0, the Direction value output will be 2.
Ports¶
- Left
- An integer input port providing the input value for the left direction, any non-0 value will be considered movement in that direction.
- Right
- An integer input port providing the input value for the right direction, any non-0 value will be considered movement in that direction.
- Up
- An integer input port providing the input value for the up direction, any non-0 value will be considered movement in that direction.
- Down
- An integer input port providing the input value for the down direction, any non-0 value will be considered movement in that direction.
- Direction
- An integer output port, one of the four direction parameter values will be output on this port depending on the input data and the Vertical Priority parameter.
Parameters¶
- Vertical Priority
- A boolean value indicating which axis to give priority to if diagonal movement is indicated. If checked, up/down will get priority, otherwise left/right will.
- Left
- A constant integer value that will be output on the Output port if the inputs indicate movement left.
- Right
- A constant integer value that will be output on the Output port if the inputs indicate movement right.
- Up
- A constant integer value that will be output on the Output port if the inputs indicate movement up.
- Down
- A constant integer value that will be output on the Output port if the inputs indicate movement down.
- None
- A constant integer value that will be output on the Output port if none of the inputs indicate any movement.
