Blocks and script stacks

A stack block performs an action. A hat block starts a script. A control block can contain other blocks. Thinking in those shapes is easier than thinking about syntax.

For ordinary stack blocks, Blocks Studio reads from the top toward the bottom. A wait pauses that script; another event stack can still exist independently.

Repeat, Forever, If and If/Else have space for child blocks. Those children belong to the control structure instead of the outer stack.

Use multiple event stacks for separate jobs instead of creating one gigantic script that controls the whole game.

• One script for input.
• One script for animation.
• One script for score/game state.
