Hello,
I run my game on BB10 (porting from Android, PC). On PC Android my game images with an alpha are ok but on the playbook all alpha are darker. Something I am missing?
Code to load texture:
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, image.getWidth(), image.getHeight(), 0, GL_RGBA, GL_UNSIGNED_BYTE, image.getDatas());
Code to render a texture:
glClearColor((GLfloat)(gBackColor.r), (GLfloat)(gBackColor.g), (GLfloat)(gBackColor.b), (GLfloat)(gBackColor.a));
// Efface l'ecran et le tampon de profondeur : note: pas besoin pour le color buffer car on affcihe tout l ecran
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glLoadIdentity();
glPushMatrix();
glEnableClientState(GL_VERTEX_ARRAY);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glEnable(GL_TEXTURE_2D);
glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA);
M_Color lightDiffuse = disp_GetGlobalDiffuse();
// affect lightDiffuse
lightDiffuse *= this->mDiffuseColor;
glColor4f((GLfloat)(lightDiffuse.r), (GLfloat)(lightDiffuse.g), (GLfloat)(lightDiffuse.b), (GLfloat)lightDiffuse.a);
And finally I use glDrawArrays(....)
On PC and Android I have no problem.
Thank you
