Whoa, where did that strange path come from? It looks like you are on Mac OS, probably the latest version (High Sierra). What's your OS version number? (e.g. 10.13.0)? Something must have changed about how the OS resolves absolute paths. GP uses the absolute path of the app to find the Examples fold...

Good catch! Yes, that is definitely an error. The export app is supposed to have the same logical stage size as when you developed it in GP. (It scales when you resize the window, but it should remain 800x500 logical units.)

I'll fix this in the next release.

1. In GP, lists are just values like numbers, strings, colors, etc. The "list" block creates a list, and you can store it in a variable so you can operate on it they way you operate on Scratch lists. SimpleSi's post is a good guide. 2. GP doesn't have a block in the palette to open a file selector, ...

It sounds like the GP application got separated from the "Examples" folder. Make sure the GP app is in the GP folder that you got when you first unzipped GP. This problem sometimes arise on Mac OS 10.12 and later because you need to remove GP.app from the GP folder and put it in the Applications fol...

About 99% of the time, I prefer using if statements and returns to handle expected errors, as MSandro suggested. However, there are are a few cases when one needs a mechanism that can catch and recover from unexpected errors. For example, making a robust server that recovers from unexpected errors, ...

You're right, the "send" block does what broadcast used to do -- it allows you to send a message to a sprite or list of sprites (with an optional "data") parameter. Broadcast now means "everyone", as in Scratch. My hope is that this will the simple cases of broadcast easier to understand/discover fo...

The latest version of GP, v078, is available from http://gpblocks.org/versions/GP.zip. The only new feature is support for 64-bit Linux. This was tested on Ubuntu 14.4 and 16.4 plus a few other Linux distros. Not surprisingly, GP works best on variations of Ubuntu, such as Mint. The sound stutters a...

Thanks for reporting this. In v076 it nows gives an error message (in the debugger) rather than returning the mysterious NaN. There's a special case for -1 raised to an integer power, which is sometimes used in math equations as a way to get alternating -1 and 1 values. Maybe that should be extended...

Thanks for reporting this. WIll be fixed in v077.

This isn't a new feature in v77; it's been that way since we added user-defined methods. But I agree, it doesn't make sense to be able to specify the type of the "this" parameter. I'm hoping to rework all the method stuff, maybe in January, to minimize the use of "this" as much as possible. As you a...
