Hello, Carlos;
I can't identify the sound blocks, or are they not yet implemented?
I must have confused myself; "VCS Game Maker" has simple sound support, but blocklyVN32x has none.
Is the "Delay" block in milliseconds?
Unfortunately the "delay" block isn't implemented, yet; currently, it does nothing.
"Count with i from 1 to 10 by" block
This one loops by incrementing the selected variable from the start value to the end value.
"Map value to [0-180]" block
This one is a remainder from the BlocklyDuino tool, which I had used as a starting point for the C generation blocks. It serves as a kind of unit conversion, by converting one range of numbers to another range of numbers. Not very useful for a Visual Novel; it's there by accident.
Is there a block to generate random numbers?
Unfortunately, at the moment, no.
