me id like to know how please
here's an easy way to find them (you need Crowbar or GCFscape, which open VPKs)
you can use your own version of TF2 and look for the in-game files for the default coordinates
tf > tf_misc_dir.vpk > root > scripts
in this scripts folder you will find the tf_weapon_scattergun (and all other weapons') files
These are the same ones we use to get VTF crosshairs, smaller explosions, etc except they're in .ctx form instead of .txt (basically the same thing)
These will contain all of the game's default values so you can figure out the coordinates from there
Just keep in mind the sniper crosshair has to be moved 1 pixel down to be centered. Also the sapper + engineer build/destroy crosshairs are actually just the corner of the medigun cross, not an actual crosshair
