Graphics / Re: [SFML2] sf::Sprite::getGlobalBounds() bigger than source image?

I found the problem, it was some buggy code by me.

Graphics / [SFML2] sf::Sprite::getGlobalBounds() bigger than source image?

« on: May 24, 2012, 05:00:28 pm »

I'm developing a tank game right now and am using the GlobalBounds of my Sprites for collision detection. Why does the GlobalBounds' intersects-method register collisions when the two sprites don't actually overlap, but are several pixels apart from each other?

Graphics / [SFML 2] Sprite Vertices' Coordinates

« on: May 21, 2012, 01:53:48 am »

I'm trying to implement collision detection for rotated rectangles. I found the following for SFML 1.6:

The points in local coordinates are:
- (0, 0)
- (0, sprite.GetSubRect().GetHeight())
- (sprite.GetSubRect().GetWidth(), 0)
- (sprite.GetSubRect().GetWidth(), sprite.GetSubRect().GetHeight())

The points in global coordinates are:
- sprite.TransformToGlobal(px)
where px is one of the local points.

How do I get the local coordinates in SFML 2? Via getLocalBounds() or via getTextureRect()?

Edit: An additional question just came to my mind. Does changing the origin of a sprite change the way I have to calculate those local coordinates?

Window / Re: Incomplete Type (sf::Event) when including SFML/Graphics/Texture

Generally, you should always include the headers you need (here the one for sf::Event) and not rely on other headers to include them automatically.

Did that now. The source of my problem was a missing semicolon after my bullet class. For some reason Visual Studio did not show the error anymore when I removed the Texture.hpp include but the program didn't actually compile like that.

Window / Incomplete Type (sf::Event) when including SFML/Graphics/Texture

« on: May 20, 2012, 07:38:02 pm »

My project setup is as follows:

A game.cpp which contains the game loop etc. It includes "Player.h", my player class, "Bullet.h" and <SFML/Graphics.hpp>. The Player.h file includes <SFML/Graphics/Sprite.hpp>, so does the "Bullet.h" (ifndef protection is in place). Now if I include <SFML/Graphics/Texture.hpp> in my "Bullet.h" Visual Studio suddenly marks my Usage of sf::Event in my gameloop as erroneous, stating that "An incomplete type is not allowed".  When I don't include <SFML/Graphics/Texture.hpp>, I don't get this error and the program compiles just fine (if I don't use sf::Texture in my Bullet class obviously). What's wrong here?
