Collision not detected
« on: December 23, 2015, 12:00:30 pm »
Hi,
ok let me explain situation.
i have player sprite and blade.
my player position is 500,225.
blade position is 4500,250.

now i want to detect collision when blade touch the player , thats how i do it:
        FloatRect PlayerBound = sp.getGlobalBounds();
                        FloatRect BladeBound = blade_SP.getGlobalBounds();


                        if (PlayerBound.intersects(BladeBound)) {
                                u = 4;
                                death = 1;
                                cout << "detected";
                        }
i just follow the tutorial in sfml learning section why this will not work at all? what im doing wrong?
thanks

There is absolutely not enough information here to understand your problem.
Please post a complete and minimal example and describe the errors you are having.
You should also read that entire thread.

ok more info:


this is blade and player two sprites and this is my collision detection codes:

// player death
                        FloatRect PlayerBound = sp.getGlobalBounds();
                        FloatRect BladeBound = blade_SP.getGlobalBounds();


                        if (PlayerBound.intersects(BladeBound)) {
                                u = 4;
                                death = 1;
                                cout << "detected";
                        }
                        if (death == 1) {
                                if (DieOn <= 30) {
                                        window.draw(play.dieA.DoAnimation(np));
                                        DieOn++;

                                }
                                if (DieOn == 30)
                                        state = 2;
                               
                        }
                        // player death
I try say :
when playerBound touch BladeBound initialize some variables and do the dying animation
window.draw(play.dieA.DoAnimation(np));
but i dont know why blade always pass the player and collision code will not work.  :-[
i hope i have make it clear.
thanks

Just post problematic rectangle coordinates and size. But it seems that there is a problem with object physics (high speed relative to update interval), but not with FloatRect
