If you simply request the str() representation of the param, it is formatted correctly.

This means that you don’t need to check or handle whether the user entered a plain string, a string with a code trigger character ( $), or the field was of type code in the first place. In particular, the _str_ representation of a Param will format its value (.

A very useful thing that Params know is how to create a string suitable for writing into the. The Param() class is defined in .Param(). You need name, startTime, duration, and several other params to be defined or you get errors. Self.params is a key construct that you build up in _init_. Yet other names get derived from user-entered names, like trials –> thisTrial. You will do a bunch of this kind of call in your newcomp.py file: Your new Component writes code into a buffer that becomes an executable python file, xxx_lastrun.py (where xxx is whatever the experimenter specifies when saving from the Builder, xxx.psyexp). For example, this was necessary for the ApertureComponent, to pass allowStencil=True to the window creation. Very occasionally, you may also need to edit settings.py, which writes out the set-up code for the whole experiment (e.g., to define the window). Localized values must not be used elsewhere in a component definition.

label fields of params should always be set to a localized value, either by using a dict entry such as _localized, or via the globally available translation function, _(‘message’). It contains mappings that allow a strict separation of internal string values (= used in logic, never displayed) from values used for display in the Builder interface (= for display only, possibly translated, never used in logic). If your component will need other libs, call () (see e.g., parallelPort.py).Īt the top of a component file is a dict named _localized.

Inheriting from VisualComponent (which in turn inherits from BaseComponent) adds default visual params, plus arranges for Builder scripts to import psychopy.visual. Some of these fields may need to be overridden (e.g., durationEstim in sound.py). def writeInitCode ( self, buff ): def writeRoutineStartCode ( self, buff ): def writeFrameCode ( self, buff ): def writeRoutineEndCode ( self, buff ):Ĭalling super() will create the basic default set of params that almost every component will need: name, startVal, startType, etc. There are three main steps, the first being by far the most involved.Ĭlass NewcompComponent ( BaseComponent ): # or (VisualComponent) def _init_ (. Take a look at several existing Components (such as image.py), and key files including _base.py and _visual.py. You’ll mainly be working in the directory …/psychopy/experiment/components/. (If this doesn’t mean anything to you then see Using the repository ) To get started, Working on a new feature for the development of this component. Many of these will come simply from subclassing the _base or _visual Components. beginning of the Routine, every frame, end of the study etc…).

This makes it straightforward to add new ones.Īll you need to do is create a list of parameters that the Component needs to know about (that will automatically appear in the Component’s dialog) and a few pieces of code specifying what code should be called at different points in the script (e.g. Builder Components are auto-detected and displayed to the experimenter as icons (in the right-most panel of the Builder interface panel).
