Control
In block coding, control blocks manipulate the flow of the program.
They can wait for a set time, detect keyboard input, print logs, and more.
Wait
Waits for the specified time (in seconds) and then runs the next command.
Parameters
| Name | Kind | Description | Range / Type | Default |
|---|---|---|---|---|
| sec | Input (field) | Wait time — literal number (e.g. Utils.wait(0.5)) | Real number ≥ 0 | - |
| sec | Input (block) | Wait time — variable/expression (e.g. Utils.wait(time)) | Real number ≥ 0 | - |
Python
python
# field sec = 2 → used as is (in seconds)

# variable input
Utils.wait(myVar)Wait one frame
Pauses the execution of the program for one frame (about 0.001 seconds).
Parameters
