Hello,
I feel like I’m missing something obvious, but I don’t understand the meaning of the “with output” part of several code blocks. For example, Sound.Play and Alert.Show both include a line that says “with output” that does not seem to have any identifiable purpose.
Thanks in advance for any help!
The output content varies from block to block.
For Sound–>Play, the output is error which is a text string containing an error message about why the sound file could not be played.
For Alert–>Show, the output tells you whether or not the user has clicked the confirmation button.
You can drag the green blocks into Label display blocks, If/Then blocks, etc. if you need that information.
Thank you for the explanation! I now understand that the “with output” line refers to the block below it. I was thinking they were separate. It’s odd they’re on different lines.
Now I’m trying to figure out how to do some basic canvas manipulation. I thought I’d try to get circles drawn wherever the user touches. However, I seem to misunderstand what the “pointer” block’s purpose is, shown in the code below:
What is the “pointer” block for and how is it used? By using it to set a label’s text, it just shows “0”, implying it’s empty?
I’ve never used the canvas so I’m probably not the best person to answer but I’ll take a crack at it anyway. It looks like you’re using it correctly with pointer’s x and pointer’s y. But pointer would be an object with various properties so trying to view it with a Label won’t work (or will return an error).
I would try setting a Label’s Text to pointer’s x or pointer’s y and see if it’s returning values you are expecting.
The documentation looks a little different than what you have: https://docs.thunkable.com/motion#get-pointer-value
Thank you both for the quick replies! Unfortunately, I wasn’t clear in my question. I had read the documentation and seen that example, but am confused on what the point of the “pointer” parameter is. I’ll try to rephrase: if you’re supposed to access pointers through Canvas1.activePointer then why have a pointer parameter? What is it for?
This parameter “pointer” contains the number of fingers that touch the screen at the same time. It can be from 1 to 4 and more touches. If one finger is touched, it is equal to the active pointer.
Thank you!
