Setting Direction Change parameters
Firstly, if you want to turn all Direction Change options off, uncheck the box labelled ‘Change direction’. This means that the direction of Entities is not affected by the Drift Zone, although their speed will still be affected by any parameters you have set.
To set Direction Change parameters:
Select one of the three options:
- Linear – enter a value to define the angle (0° to 360°) in which Entities will drift or drag and move the Drift Zone’s arrow in the model.
- Random Deviation – this causes Entities to move in a defined direction according to a defined probability. Enter a value for the Max Deviation Angle (this is the maximum direction-change allowed between steps) and then enter a Change Probability value (this is a percentage and defines the probability of Entities changing direction in the angle of deviation).
- Circular–this makes the Drift Zone circular. Select either Clockwise or Counter Clockwise to set the direction of the Drift Zone and enter values for X and Y coordinates in the boxes labelled Centred On. You can also change the centre by clicking and dragging the central node of the Drift Zone in the model.
