# Migrating |
|
|
|
## Migrating to Release 11 |
|
|
|
### Agent virtual method deprecation |
|
|
|
- `Agent.CollectDiscreteActionMasks()` was deprecated and should be replaced with `Agent.WriteDiscreteActionMask()` |
|
|
|
- `Agent.Heuristic(float[])` was deprecated and should be replaced with `Agent.Heuristic(ActionBuffers)`. |
|
|
|
- `Agent.OnActionReceived(float[])` was deprecated and should be replaced with `Agent.OnActionReceived(ActionBuffers)`. |
|
|
|
- `Agent.GetAction()` was deprecated and should be replaced with `Agent.GetStoredActionBuffers()`. |
|
|
|
|
|
|
|
The default implementation of these will continue to call the deprecated versions where appropriate. However, the |
|
|
|
deprecated versions may not be compatible with continuous and discrete actions on the same Agent. |
|
|
|
|
|
|
|
### BrainParameters field and method deprecation |
|
|
|
- `BrainParameters.VectorActionSize` was deprecated; you can now set `BrainParameters.ActionSpec.NumContinuousActions` |
|
|
|
or `BrainParameters.ActionSpec.BranchSizes` instead. |
|
|
|
- `BrainParameters.VectorActionSpaceType` was deprecated, since both continuous and discrete actions can now be used. |
|
|
|
- `BrainParameters.NumActions()` was deprecated. Use `BrainParameters.ActionSpec.NumContinuousActions` and |
|
|
|
`BrainParameters.ActionSpec.NumDiscreteActions` instead. |
