Eventos#
Introducción#
An event is a starting signal for a set of blocks. Events blocks in VEXcode VR let different sets of blocks begin at different times. For example, one set of blocks can start when the project begins, and another can start when a signal is sent from somewhere else in the project.
when started – Runs the attached stack of blocks when the project starts.
when I receive event – Runs the attached stack of blocks when a specific event is broadcast.
broadcast event – Triggers an event without pausing other blocks.
broadcast event and wait – Triggers an event and pauses other blocks until the event’s tasks complete.
cuando empezó#
The when started hat block starts running the blocks below it when the project begins. Every project needs at least one when started block — without it, the blocks below it will not run. Multiple when started blocks can be used to run different sets of blocks at the same time.
