Vector2df

[Reck]

I'm currently looking for a way to make a grid where i can detect collisions or mouseclicks on certain gridtiles. I've been reading around, and it seems i should be able to use Vector2df. However, i have no clue how to use this.
I would love if someone could give me an example! :-)

There isn't much need to use vectors to figure out which tile was clicked.

If your tiles are 50x50(Like in your other post) then you just take mousepos.x / 50 and mousepos.y/50 and that'll get you the (x,y) coords of the tile you clicked.

As for collision, it's a little more complex and depends entirely on what kind of objects you're using, how you represent them, etc.
