Subject: gameplay: the game now pauses while the door opening animation is playing.
X-Git-Url: https://git.krickl.dev/?a=commitdiff_plain;h=e7c192d871569922505ff62a400f1538d31f3e4f;p=gbrg%2F.git

gameplay: the game now pauses while the door opening animation is playing.

For this a new special flag to pause update was added.
This pause needs to be handeled in update routines.
This is done to keep rendering some objects while not processing gameplay code.
