示例1: draw
void TouchButton::draw(DrawBuffer &db, uint32_t color, uint32_t colorOverlay)
{
float scale = 1.0f;
if (isDown_) {
color |= 0xFF000000;
colorOverlay |= 0xFF000000;
scale = 2.0f;
}
scale *= scale_;
// We only mirror background
db.DrawImageRotated(imageIndex_, x_ + w_*scale_/2, y_ + h_*scale_/2, scale, rotationAngle_, color, mirror_h_);
if (overlayImageIndex_ != -1)
db.DrawImageRotated(overlayImageIndex_, x_ + w_*scale_/2, y_ + h_*scale_/2, scale, rotationAngle_, colorOverlay);
