Use overridable variables in components

parseJson gives no error message

parseJson is.a very useful and powerful function, but it doesn't do all you might expect of it (yet, hopefully).

Sending and receiving mismatched messages

You can send messages in different ways, but Protopie requires you to receive them in the matching way. A common (and easy) mistake is to send a message to a 'parent' while wanting to receive it from the current scene.

How to inspect variables inside a component

Even all-Scenes variables are not accessible inside a component. And this can lead to hard to find errors when a variable with the same name is used in a component, but its value is not sync'd with the scenes.

Use Variables

Variables are very powerful simplifying tool and they do not seem to have any impact on Protopie's performance.

Sending messages to two places

Whilst it is important to be careful in sending messages to the right places, it is also very powerful to send a message to two different places at the same time (or maybe with a small delay).

Playing with time

A message sent to the current scene will be received by the object that sent it. But a message sent to Protopie Studio (Connect) will not be received by the pie that sent it. B ut what if there is nothing out there to respond to it?

Viewing variables within Components

The variable debugger doesn't work when the variable that needs to be viewed is inside a component. There are two relatively easy ways to deal with this.

The wrong variable type

This pitfall is not a big deal, but it can waste you time as you try to track down why your variable seems to have the wrong value (or no value). It can also bite you in a formula where your variable is of the wrong type for the formula.
