From feedd6c615ae168a9934500932a8af9538f307f6 Mon Sep 17 00:00:00 2001 From: Eoin O'Neill Date: Fri, 9 Nov 2018 18:44:58 -0800 Subject: [PATCH] Update RichTextLabel to support real time effects and custom BBCodes. Added a new ItemFX type to RichTextLabel which supports dynamic text effects. RichTextEffect Resource Type was added which can be extended for more real time text effects. --- scene/gui/rich_text_effect.cpp | 122 +++++++++ scene/gui/rich_text_effect.h | 87 +++++++ scene/gui/rich_text_label.cpp | 464 +++++++++++++++++++++++++++++++-- scene/gui/rich_text_label.h | 150 ++++++++++- scene/register_scene_types.cpp | 1 + 5 files changed, 795 insertions(+), 29 deletions(-) create mode 100644 scene/gui/rich_text_effect.cpp create mode 100644 scene/gui/rich_text_effect.h diff --git a/scene/gui/rich_text_effect.cpp b/scene/gui/rich_text_effect.cpp new file mode 100644 index 000000000000..8d9b8ad1e0ae --- /dev/null +++ b/scene/gui/rich_text_effect.cpp @@ -0,0 +1,122 @@ +/*************************************************************************/ +/* rich_text_effect.cpp */ +/*************************************************************************/ +/* This file is part of: */ +/* GODOT ENGINE */ +/* https://godotengine.org */ +/*************************************************************************/ +/* Copyright (c) 2007-2019 Juan Linietsky, Ariel Manzur. */ +/* Copyright (c) 2014-2019 Godot Engine contributors (cf.
