From 7277cfec9c286b1ec667888b1ea1f485f7a74304 Mon Sep 17 00:00:00 2001 From: Kelly Rauchenberger Date: Wed, 23 May 2018 22:40:31 -0400 Subject: dropping a lamp includes a dash dropping a lamp now sprinkles dust in the same way that popping a lamp does. only dust sprinkled from dropping/popping a lamp will pop lamps -- dust from movement will not. pressing esc quits the game. SDL errors now output a message. --- src/main.cpp | 275 ++++++++++++++++++++--------------------------------------- 1 file changed, 93 insertions(+), 182 deletions(-) (limited to 'src/main.cpp') diff --git a/src/main.cpp b/src/main.cpp index 2fc610b..1b7d198 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -5,6 +5,7 @@ #include #include #include +#include class sdl_error : public std::logic_error { public: @@ -44,10 +45,10 @@ enum class Tile { Lamp };
