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);
});
```
A previous change fixed compatibility with Scratch 2 removing 3's
unintentional scope leaking. This furthers that change so that
procedures with no parameters will also not accidentally use values in
other procedure stacks.
This caused a local variable monitor to try running its thread on a different sprite, causing a new local variable to be created with the same monitor id.
This was previous behavior, but the previous commit which prevents restarts based on _steppingInterval truthiness broke it because clearInterval does not modify the value of _steppingInterval
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.
Threads are now removed after every "inner" step. Any thread that
reaches its DONE conditions is immediately removed instead of requiring
an extra step to remove it. As such tests that check the number of
threads have been updated to consider this.
When all threads are looped, finished threads must be removed so
threads that are waiting for those to complete and be removed may
continue executing. This effects broadcast and wait for example. The
threads created by broadcast and wait can finish in the same tick and
must be removed from the list of threads so that broadcast and wait
knows to stop waiting.
Use getProcedureParamNamesIdsAndDefaults to get the defaults along with
names and ids so defaults may be set for a procedure call if the
parameter is not provided.
