From b2841ce19494d8b34ef2fc13dd92c827fc1d2cc6 Mon Sep 17 00:00:00 2001 From: Eduardo Rodrigues Date: Thu, 14 Apr 2022 00:07:29 -0300 Subject: [PATCH] Improve description for GDScript built-in range Rewrites the definition of how the function works. Reworks the style of the examples and adds a negative range example. Changes the while loop to a range loop in the array backwards example. --- modules/gdscript/doc_classes/@GDScript.xml | 29 ++++++++++------------ 1 file changed, 13 insertions(+), 16 deletions(-) diff --git a/modules/gdscript/doc_classes/@GDScript.xml b/modules/gdscript/doc_classes/@GDScript.xml index d0926d317be9..70151c4d2159 100644 --- a/modules/gdscript/doc_classes/@GDScript.xml +++ b/modules/gdscript/doc_classes/@GDScript.xml @@ -184,27 +184,24 @@ - Returns an array with the given range.
