鹿的電腦圖學筆記week15

 Step01撥聲音:

1.file-new-empty file再改檔名.cpp

2.寫入

#include <windows.h>

#include <stdio.h>

int main(){

    printf("playsound()前\n");

    PlaySound("bb.wav",NULL,SND_SYNC);

    printf("playsound()後\n");

}

2.Settings-Compiler-Linker settings

加入winmm

3.去https://sound-effects.bbcrewind.co.uk/search尋找想要的wav檔

3.下載後移到執行資料夾

4.執行結果(wav先改成跟下載的檔案同名

Step02:

1.file-new-empty file再改檔名.cpp

2.寫入

#include <windows.h>

#include <stdio.h>

int main(){

    PlaySound("do.wav",NULL,SND_SYNC);///ASYNC不等待

    PlaySound("re.wav",NULL,SND_SYNC);

    PlaySound("mi.wav",NULL,SND_SYNC);

}

3.wav檔移到執行資料夾

4.要記得寫成SYNC(寫ASYNC不等待會出錯

4.改寫成

#include <windows.h>

#include <stdio.h>

int main(){

    PlaySound("NHU05082251.wav",NULL,SND_ASYNC);///不等待執行較快，適合互動

    while(1){

        printf("輸入數字: ");

        int N;

        scanf("%d",&N);

        if(N==1)PlaySound("do.wav",NULL,SND_SYNC);///ASYNC不等待

        if(N==2)PlaySound("re.wav",NULL,SND_SYNC);

        if(N==3)PlaySound("mi.wav",NULL,SND_SYNC);

    }

}

Step03 mp3:

1.下載CMP3_MCI.h再移到執行資料夾

2.file-new-empty file再改檔名.cpp

3.寫入

#include "CMP3_MCI.h"

#include <stdio.h>

CMP3_MCI mp3;

int main(){

    mp3.Load("NHU05082251.wav");

    mp3.Play();

    

    printf("輸入數字(wav停止) :");

    int N;

    scanf("%d",&N);

}

Step04 :

1.複製上週程式

#include <GL/glut.h>

#include <stdio.h>

float angle[20],oldX=0;

int angleID=0;

FILE * fout=NULL,*fin=NULL;

void myWrite(){

    if(fout==NULL) fout=fopen("file.txt","w");

    for(int i=0;i<20;i++){

        printf("%.1f ",angle[i]);

        fprintf(fout,"%.1f ",angle[i]);

    }

    printf("\n");//跳行

    fprintf(fout,"\n");

}

void myRead(){

    if(fout!=NULL){fclose(fout);fout=NULL;}

    if(fin==NULL) fin=fopen("file.txt","r");

    for(int i=0;i<20;i++){

        fscanf(fin, "%f", &angle[i]);

    }

    glutPostRedisplay();//重畫畫面

}

void keyboard(unsigned char key,int x,int y){

    if(key=='r')myRead();

    if(key=='0')angleID=0;

    if(key=='1')angleID=1;

    if(key=='2')angleID=2;

    if(key=='3')angleID=3;

}

void mouse(int button,int state,int x,int y){

    oldX=x;

}

void motion(int x,int y){

    angle[angleID]+=(x-oldX);

    myWrite();

    oldX=x;

    glutPostRedisplay();///重畫畫面

}

void display(){

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glColor3f(1,1,1);

    glRectf(0.3,0.5,-0.3,-0.5);///身體

    glPushMatrix();

        glTranslatef(0.3,0.4,0);///手臂掛到身體

        glRotatef(angle[0],0,0,1);///旋轉

        glTranslatef(-0.3,-0.4,0);///把手臂旋轉中心放到中心

        glColor3f(1,0,0);///紅

        glRectf(0.3,0.5,0.7,0.3);///上手臂

        glPushMatrix();

            glTranslatef(0.7,.4,0);

            glRotatef(angle[1],0,0,1);///旋轉

            glTranslatef(-0.7,-0.4,0);///把手臂旋轉中心放到中心

            glColor3f(0,1,0);///紅

            glRectf(0.7,0.5,1.0,0.3);///下手臂

        glPopMatrix();

    glPopMatrix();

    glPushMatrix();

        glTranslatef(-0.3,0.4,0);///手臂掛到身體

        glRotatef(angle[2],0,0,1);///旋轉

        glTranslatef(0.3,-0.4,0);///把手臂旋轉中心放到中心

        glColor3f(1,0,0);///紅

        glRectf(-0.3,0.5,-0.7,0.3);///上手臂

        glPushMatrix();

            glTranslatef(-0.7,.4,0);

            glRotatef(angle[3],0,0,1);///旋轉

            glTranslatef(0.7,-0.4,0);///把手臂旋轉中心放到中心

            glColor3f(0,1,0);///紅

            glRectf(-0.7,0.5,-1.0,0.3);///下手臂

        glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc,char** argv){

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutInitWindowSize(600,600);

    glutCreateWindow("week15_ANGLE_TRT_Again");

    glutKeyboardFunc(keyboard);

    glutMouseFunc(mouse);

    glutMotionFunc(motion);

    glutDisplayFunc(display);

    glutMainLoop();

}

2.在motion註解

///myWrite();

3.keyboard寫入

if(key=='s')myWrite();

s:寫好才存入一個動作

3.小技巧:可以複製紀錄後的動作重複執行，動作就會增加
