This is a function include that has a few functions to help make things better. As of right now it's pretty small but contains some pretty useful things to help renovate your gamemode. I shall maintain this include and add anything people would be interested in having on their server. It's kind of a 'Make It Comfortable' include, but these are slightly more useful and are optimized to the best of my abilties.
Functions
SavePVars(playerid) and LoadPVars(playerid)
This function will save every 'PVar' that has been assigned to the player without discrimination. This, in combination with LoadPVars, means you can have a player come and go and be right where he was when he left. Even if he was on the losing team of a fight or rotting in jail.
*Removed/Changed -- v1.0 only
IsPlayerLookingAtPoint(playerid,Float:X,Float:Y,Fl oat:Z,Float:ViewWidth,Float:ViewHeight);
This major function The real reason why I even wanted to post this include =p is used to determine weither or not a player is looking at a position.
Using your head as an aiming scope (right about where the eyes are) this function will return 1 if what you're looking at the position.
ViewWidth and ViewHeight are used as a view cone from the player's head to decrease required accuracy with the aim. I find that 22.5 degrees (45 degrees from left to right) is a fair enough view cone for width (horizontal), and 10 degrees (20 degrees top to bottom) is good for height (vertical)
With this you can tell if someone head shots an NPC!
*New v1.1 and up
IsPlayerLookingAtPlayer(playerid,playerid2);
This returns 1 if the player is looking at playerid2. Unfortunately, because of the offset that the reticle is at, it's only accurate if based on the center of the screen (right where the player's head is, generally)
Hopefully, the following script will show the player's health in green when looking at that player
