From 34051ffdca091ad3971c1382c71c5fc58b7ade0f Mon Sep 17 00:00:00 2001 From: Mikko Rasa Date: Wed, 22 May 2019 23:30:59 +0300 Subject: [PATCH] Merge CameraControl functionality into other classes Rather than each stage having a separate animation player for animating its camera, use a central player in the demo. This allows more easily animating other objects as well. --- source/animate.cpp | 52 +++++++++++++++++++++++++++++++++++++++ source/animate.h | 35 ++++++++++++++++++++++++++ source/cameracontrol.cpp | 43 -------------------------------- source/cameracontrol.h | 53 ---------------------------------------- source/demo.cpp | 12 +++++++++ source/demo.h | 21 ++++++++++++++++ source/sequencer.cpp | 3 +++ source/stage.cpp | 52 ++++++++++++++++++++++++++++++++++++++- source/stage.h | 32 ++++++++++++++++++++++-- 9 files changed, 204 insertions(+), 99 deletions(-) create mode 100644 source/animate.cpp create mode 100644 source/animate.h delete mode 100644 source/cameracontrol.cpp delete mode 100644 source/cameracontrol.h diff --git a/source/animate.cpp b/source/animate.cpp new file mode 100644 index 0000000..d74c239 --- /dev/null +++ b/source/animate.cpp @@ -0,0 +1,52 @@ +#include "animate.h" +#include "demo.h" + +using namespace std; +using namespace Msp; + +Animate::Animate(): + target(0), + anim(0), + player(0) +{ } + +Animate::Animate(GL::Placeable &t, const GL::Animation &a, GL::AnimationPlayer &p): + target(&t), + anim(&a), + player(&p) +{ } + +void Animate::validate() const +{ + if(!target) + throw logic_error("null target"); + if(!anim) + throw logic_error("null animation"); + if(!player) + throw logic_error("null player"); +} + +void Animate::start(float, float d) +{ + float speed = (d ?
