示例1: rasterize
void BlockPhysicsComponent::rasterize(Polygon2 const &polygon)
{
Polygon2 localPolygon;
for (int i = 0; i < polygon.getSize(); ++i) {
b2Vec2 worldPoint(polygon.vertices[i].x, polygon.vertices[i].y);
b2Vec2 localPoint = body_->GetLocalPoint(worldPoint);
localPolygon.vertices.push_back(Vector2(localPoint.x, localPoint.y));
}
Box2 bounds = localPolygon.getBoundingBox();
int minX = int(10.0f * bounds.p1.x + 0.05f);
int minY = int(10.0f * bounds.p1.y + 0.05f);
int maxX = int(10.0f * bounds.p2.x + 0.05f);
int maxY = int(10.0f * bounds.p2.y + 0.05f);
for (int y = minY; y <= maxY; ++y) {
