Hello,
i'm trying to write my own animation class. My class derive from sf::Drawable and sf::Transformable. Problem is, when i use "setPosition" for example "setPosition(32,48)" animation is rendered at 64,96. There's some code:
void ANIMATION_BASE::draw(sf::RenderTarget& target, sf::RenderStates states) const
{
if(m_state!="") {
std::map<const sf::String, ANIMATION_SET>::const_iterator it;
it=m_animationsSet.find(m_state);
sf::Vector2f pos;
pos=getPosition();
sf::VertexArray vertex_array(sf::Quads, 4);
vertex_array[0].position=pos;
vertex_array[1].position=pos+sf::Vector2f(it->second.frameSize.x, 0);
vertex_array[2].position=pos+sf::Vector2f(it->second.frameSize.x, it->second.frameSize.y);
vertex_array[3].position=pos+sf::Vector2f(0, it->second.frameSize.y);
sf::FloatRect frame;
if(it->second.orientation) {
frame.left=it->second.textureRect.left+(m_frame*(it->second.frameSize.x));
frame.top=it->second.textureRect.top;
} else {
frame.left=it->second.textureRect.left;
frame.top=it->second.textureRect.top+(m_frame*(it->second.frameSize.y));
}
frame.width=it->second.frameSize.x;
frame.height=it->second.frameSize.y;
vertex_array[0].texCoords=sf::Vector2f(frame.left, frame.top);
vertex_array[1].texCoords=sf::Vector2f(frame.left+frame.width, frame.top);
vertex_array[2].texCoords=sf::Vector2f(frame.left+frame.width, frame.top+frame.height);
vertex_array[3].texCoords=sf::Vector2f(frame.left, frame.top+frame.height);
states.transform*=getTransform();
states.texture=m_texture;
target.draw(vertex_array,states);
}
}
Everything is ok when i delete this line:
states.transform*=getTransform();
But if i do this, i cant rotate, scale etc.
It's my first time with Vertex so maybe i do something wrong
EDIT:
Finally i found whats wrong. Problem is here:
pos=getPosition();
I was thinking that i need to set vertices in global coords. And now i just realize that i need to set everything locally and then magically everything is rendered in right place when i do "window.draw(animation); ". This Library is awesome!
