This is done by adding a new element "customFieldTypes" to the extension info structure. Ex:
```
customFieldTypes: {
angleField: {
implementation: { fromJson: options => new AngleField(options) },
output: 'number',
outputShape: 2,
}
}
```
Field types are defined by an implementation that has to match what is expected by ScratchBlocks.Field.register and its output and shape.
src/engine/runtime.js has been updated to handle the new "customFieldTypes"-field:
- Existing (global) field types cannot be overridden
- New fields are "namespaced" to the extension in the same way as opcodes are.
Once the custom field type has been picked up by scratch-vm a "EXTENSION_FIELD_ADDED" event is emitted.
It is then up to the hosting app to call ScratchBlocks.Field.register to register the field type with ScratchBlocks. Ex:
```
vm.addListener('EXTENSION_FIELD_ADDED', fieldInfo => {
this.ScratchBlocks.Field.register(fieldInfo.name, fieldInfo.implementation);
});
```
This change makes the VM's `setLocale` method call `refreshBlocks` even
when not changing the language, though it still skips an unnecessary
call to `formatMessage.setup` in this case.
And emit it whenever we think the project has changed. Try to not emit it when a change has happened internally that shouldn't affect the serialized project.
This iteration fires the event too frequently, e.g., when switching sprites. This is meant as a simple initial implementation that can be improved.
Resolves#1601. Does not include the project JSON since that would require knowledge of a project ID, which the VM has not been responsible for so far.
For now, it is the responsibility of the consumer to determine if these assets should be saved or not. Otherwise the VM would need to be responsible for saving, which has been out of its scope.
