prob
Description
Creates a table of weighted numeric transitions. A
message causes the weighting, and a potential transition, to be calculated.Examples
Discussion
prob accepts lists of three numbers in its inlet. The third number represents the weight of the probability of going from states represented by the first two numbers. For example, would mean that there is a weight of 4 in going from state 1 to state 2. When prob receives a , it makes a random jump from its current state to another state based on its current weighting of transitions. If a transition can be made, the new state is sent out the left outlet. If not, a is sent out the right outlet. For any particular state, the weights of all possible transition states are summed. Thus if a state could jump to three states that had weights of 3 4 and 1, the first one (3) would occur 37.5% of the time, the second 50% of the time, and the third 12.5%. Note that any state can make a transition to itself with a list of the form (state state weight).
Arguments
None.
Attributes
embed [int] (default: 0)
When non-zero (on), the contents of prob will be saved as part of the patcher which contains it. When zero (off, default) prob will forget its contents when the patcher is closed.

hidden [int] (default: 0)
Toggles whether an object is hidden when the patcher is locked.

Sets the position and size of the object in the patcher window.
position [2 floats]
Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.
presentation [int] (default: 0)
Sets whether an object belongs to the patcher's presentation.
presentation_rect [4 floats] (default: 0. 0. 0. 0.)
Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.
rect [4 floats]
Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).
size [2 floats]
Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.
