Referencia de expresiones

Las expresiones se pueden añadir cuando ves este botón al lado de algún campo de texto:

El botón de la izquierda indica una "expresión de cadena" (un texto)
El botón derecho indica una "expresión numérica" (número)

Esta página es una referencia de todas las expresiones que se pueden usar en GDevelop, agrupadas por la extensión, objeto o comportamiento al que pertenecen también. Cuando se escribe "Objeto", debe ingresar un nobre para el objeto.Aprenda más aquí sobre cómo escribir expresiones.

Note

Las expresiones también son llamadas a veces funciones, como en matemáticas.
