From c7e5dd9ef04a5bd67b48f6bac3836651d1e25488 Mon Sep 17 00:00:00 2001 From: Hugo Locurcio Date: Tue, 15 Oct 2019 10:23:38 +0200 Subject: [PATCH] Add primary grid lines to the 2D editor A "primary" line is drawn every 8 steps by default, which makes it easier to measure distances for snapping. This value can be configured in the Configure Snap dialog. --- editor/plugins/canvas_item_editor_plugin.cpp | 104 +++++++++++++++---- editor/plugins/canvas_item_editor_plugin.h | 1 + 2 files changed, 82 insertions(+), 23 deletions(-) diff --git a/editor/plugins/canvas_item_editor_plugin.cpp b/editor/plugins/canvas_item_editor_plugin.cpp index 7659363cdf..9502ffd19f 100644 --- a/editor/plugins/canvas_item_editor_plugin.cpp +++ b/editor/plugins/canvas_item_editor_plugin.cpp @@ -67,6 +67,7 @@ class SnapDialog : public ConfirmationDialog { SpinBox *grid_offset_y;
