Create company logo/sound for entry to application....
Posted: Sun May 10, 2009 4:22 pm
I thought some of you may appreciate this, as part of my Game Logic engine I wanted to think of a way to render my company logo, play intro sound and then go to menu state, whilst it may seem very simple it was rather complex to think of the best way to implement it; anyway, enough talk - the code is self explanitary and commented and is an example of how you can do this (note, this is a basic example you can improve upon it as much as you like):
LogoScene.h
main.cpp
LogoScene.h
Code: Select all
/*
Everything is declared and defined
for Logo scene as it is simple and small
and thus deemed pointless giving it an
implementation file
*/
#ifndef LOGO_H // header guard
#define LOGO_H
#include <irrlicht.h>
#include <irrKlang.h>
class LogoScene
{
protected:
//for sound declaration used in both methods
irrklang::ISound* snd;
//temp int for both methods
int introSceneCount;
public:
void createIntroScene()
{
device->setWindowCaption(L"Displaying company logo and playing music");
//play a sound, with params no loop and tracking enabled
snd = engine->play2D("THE SOUND FILE",false,false,true);
//create Logo Image
irr::gui::IGUIImage* img = env->addImage(driver->getTexture("COMPANY IMAGE")
,irr::core::position2d<irr::s32>(0,10));
//disable mouse visibillity
device->getCursorControl()->setVisible(false);
}
//used to check if the sound is finished [to be used in main render loop]
void checkIntroSceneFinishParams()
{
//used as a reference counter
/*
Wait for logo rendering/music
to finish and then call the menu state
*/
if(snd->isFinished() && introSceneCount == 0)
{
env->clear();
device->getCursorControl()->setVisible(true);
//Code for menu state here
//break loop condition so loop is executed 1 time
introSceneCount = 1;
}
}
}Logo;
