OpenGL yoyo programı sorunları

Question

Çalışmak için yoyo programımı almada sorun yaşıyorum; Hareketli ve dönen yoyo ile birlikte ilerlemek için gittikçe büyüyen ve küçülen bir dizim var, ama ben yoyo ile birlikte hareket eden iplerim var. Yoyo yukarı ve aşağı hareket ederken sabit kalan dizgiye ihtiyacım var. Bir tuşa da tahsis edilmiş dize ve yoyo hareketlerine sahip olmak zorundayım. Koduma yardım etmeme yardım eder misin? (Ayrıca cansız yoyo lütfen bağışlayın; bunu tasarlamadan önce programlamayı bitirmek istedi) benim sorun çözüldü

. Çok gibi hareket işlevi içinde draw_string() ve seconddisplay() işlev ayrıldı gitti:

} 

glPushMatrix(); 
glTranslatef(360+deltax, 80+deltay, 0.0); 
glRotatef(spin,0.0,0.0,1.0); 
glTranslatef(-360,-80, 0.0); 
secondDisplay(); 
glPopMatrix(); 
glPushMatrix(); 
glTranslatef(360+deltax, 80+deltay, 0.0); 
glRotatef(0,0.0,0.0,1.0); 
glTranslatef(-360,-80, 0.0); 
draw_string(); 
glPopMatrix(); 
drawButton(); 
glutSwapBuffers(); 
} 

I draw_string gelen sıkma kaldırıldı() 'in glRotatef.
