示例1: DrawSprite
void AnimatedSpriteRenderer::DrawSprite(SpriteSheet &sheet, glm::vec2 position, glm::vec2 size, GLfloat rotate, glm::vec3 color, int frame)
{
// Prepare transformations
this->shader.Use();
glm::mat4 model;
model = glm::translate(model, glm::vec3(position, 0.0f)); // First translate (transformations are: scale happens first, then rotation and then finall translation happens; reversed order)
model = glm::translate(model, glm::vec3(0.5f * size.x, 0.5f * size.y, 0.0f)); // Move origin of rotation to center of quad
model = glm::rotate(model, rotate, glm::vec3(0.0f, 0.0f, 1.0f)); // Then rotate
model = glm::translate(model, glm::vec3(-0.5f * size.x, -0.5f * size.y, 0.0f)); // Move origin back
model = glm::scale(model, glm::vec3(size, 1.0f)); // Last scale
this->shader.SetMatrix4("model", model);
