Set text alignment on "Display Text" block about pxt-max7219_8x8 HOT 4 CLOSED

Yeah, I totally forgot that the characters have their own widths. My bad.

I made a update with a new block. Test OK on my own device. Re-import the driver and it should be there.

The offset option in the "Display text" block allows you to print texts started at any place on the display.

A 4x 8x8 matrix has 4x8=32 columns, so offset can be set as 0 to 31 (0 = start for the first column from the left). Store your text in a variable, get its length, and set the offset as (31 - length).

You can also utilize this to do some animation effects, like scrolling texts from right to left, back and forth or blinking and stuff.

Add a new block is simple enough - but there would be adding more lines of code than above (I would have to define a new block as well). Since this driver already used up a lot of memory space of micro:bit, I am hesitate to do that now. (Maybe not until the new version of micro:bits become widely used.)

Hi Alan, thanks for the promt answer, very much appreciated.

I checked your proposal and I am not sure if I am getting it right or wrong but it doesn't work for me.

So the when I calculate 31 - length of text - let's say "10 cm", then length ("10 cm") is 5. 31 -5 is 26. Offset 26 however is not enought to show the string I want to show.

I guess I would need to have access to the width of the text instead of the length. I have seen that you have such a matrix inside your source code. Is there any way to get access from outside to this width array?

Cheers and greetings from Germany :)
