Conditions and sensing

## Conditions (if) When your program needs to make a decision, use `if`. ``` if <key (space) pressed?> then say [Jumped!] else say [Waiting] end ``` ## Sensing - `touching (edge)?` — is it touching the edge? - `key (space) pressed?` — is the key pressed? - `touching color [ ]?` — is it touching a colour? ## Comparing (Operators) `(x) > (50)`, `(x) < (50)`, `(x) = (50)`, plus `and`, `or`, `not`.
