History
- Main article: List of Obsolete Blocks#Backdrop ()
This block was in the Scratch 2.0 alpha version, but was removed in v175. However, it was brought back in Scratch 3.0, merging two other blocks.
Uses
This block is useful for choosing among several actions by the backdrop:
if <(backdrop [name v]) = [Arctic]> then
say [Let's have warm tea] for (5) seconds
else
if <(backdrop [name v]) = [Savanna]> then
say [Let's have cold water] for (5) seconds
end
end
The number option is useful for changing past multiple backdrops instantly:
switch backdrop to ((backdrop [number v]) + (10)) and wait
