collision on vertex array tile engine

[guptarohan]

Hello there,
I am making a simple 2d rpg with SFML,
I was wondering how to implement collision with my tile engine, which is based on the example on this page.
http://www.sfml-dev.org/tutorials/2.0/graphics-vertex-array.php.
How do I do the following:
a)check which tile the sprite (player) is on
b)specify which tiles are crossable
c)stop the player from going on those tiles

Thanks, Rohan

a) Divide the player's position by the size of the tiles (do this for the x and y axis). The result(as an integer) is the tile the player is currently on.

b) Have a bool variable for each tile. Have the variable be true if the tile is cross able and false if the tile is not cross able.

c) Implement a collision system using the four vertices of the tile to get the bounding box rather that the predefined getBoundingBox() function.
