How to handle collision in SFML

Posted 31 August 2011 - 12:34 PM

Ok so now that I know the basics of SFML, I would like to know how to handle standoff in SFML. I just deceit seem to detect it. And by the way I checked the wiki one but couldn't empathise it.

Thanks

Post what you have found and your attempt.

SFML doesn't specifically have standoff detection built in.

They practice however have this code sample which implements bounding boxes, bounding circles and pixel perfect collision detection.

Your other option if yous need something more than advanced is to implement a 2D physics system like Box2D.

Your other selection if you need something more advanced is to implement a 2nd physics organisation like Box2D.

And then, I have to make/include a precreated collision header file everytime I implement collision?
Isn't there an easier method for implementing collision.

Oh well I was having problems with the lawmaking. So, I went forward and grabbed Box2D instead. It is quite easier. Topic solved.

You will never get in as a game programmer with that attitude. Besides, huh?

Isn't in that location an easier method for implementing collision.

You volition never make it every bit a game programmer with that mental attitude. Also, huh?

Pitiful its simply that I become a lot of errors with information technology and afterwards ii~3hrs I become frustrated. And now it seems that there is a problem with box2d implementation besides . But if u say so then I will effort the collision code sample again!

Well I tried once again and this time I didnt try the sample test but tried my own. here is the error I got:-

one>SFML_Test.obj : error LNK2019: unresolved external symbol "public: static bool __cdecl Collision::BoundingBoxTest(class sf::Sprite const &,class sf::Sprite const &)" ([email protected]@@[electronic mail protected]@@[email protected]) referenced in function _main i>C:\Users\Arunabh\Documents\Visual Studio 2008\Projects\SFML_Test\Debug\SFML_Test.exe : fatal error LNK1120: 1 unresolved externals            

here is the code used:-

#include "resources.h" #include <SFML/Graphics.hpp> #include "Collision.h"  using namespace sf;  Image image; Sprite sprite; Image image2; Sprite sprite2;  Collision::Collision() { }   Standoff::~Collision() { }  int main() {     // Create the main rendering window     RenderWindow App(VideoMode(800, 600, 32), "SFML Graphics");  	if(!image.LoadFromFile("sprite.png")) 		return one; 	if(!image2.LoadFromFile("sprite2.png")) 		return 1;  	sprite.SetImage(paradigm); 	sprite2.SetImage(image2);  	sprite.SetCenter(16, 16); 	sprite.SetPosition(400, 300);  	sprite2.SetCenter(32, 8); 	sprite2.SetPosition(350, 300);      // Start game loop     while (App.IsOpened()) 	{         // Process events         Result eEvent;         while (App.GetEvent(eEvent))         {             // Close window : exit             if (eEvent.Type == Issue::Closed)                 App.Shut();  			if((eEvent.Type == Event::KeyPressed) && (eEvent.Fundamental.Lawmaking == Central::Correct)) 				sprite.Rotate(-20.0f);  			if((eEvent.Blazon == Event::KeyPressed) && (eEvent.Key.Code == Key::Left)) 				sprite.Rotate(+20.0f);  			if(Collision::BoundingBoxTest(sprite, sprite2)) 				sprite.SetPosition(0,0);         }          // Clear the screen (make full information technology with black color)         App.Articulate(Colour(0, 180, 255));  		App.Describe(sprite); 		App.Draw(sprite2);         // Display window contents on screen         App.Display();     }      return EXIT_SUCCESS; }
