HAMMER AI V1.1

//HAMMER AI V1.1
//By KupaTec

//AI script useful for limited rotation motor weapons such as hammers or flippers
//To use set up your motor as a DOUBLE THROW MOMENTARY SWITCH using button2 as + and button3 as -
//PLEASE BACK UP YOUR BOTS BEFORE ADDING/EDITING AI!

//Update log
//-V1.1 Released!
//--Massive thanks to Hobo_Drew for pointing out I can't code
//--Removed redundant function
//--Rewrote weapon firing detection to be cleaner and much more accurate
//--Rewrote driving sequence to make the bot a lot more stable and accurate when hitting
//--Rewrote immobilisation handling to fire weapon when attempting to move

//TODO
//-Rewrite srimech
//-Create a function to control max drive and turn speed
//-Potentially add in ability to define which buttons to use

//====================================TUNE THE AI HERE====================================
	//Distance from enemy to arm weapon
	weaponRange = 1
	//Deviation from center to fire weapon once in range
	//Min = 0, Max = 1, Default 0.05 or 13 degrees
	weaponFOV = .05
	//"Recharge" time for weapon in seconds
	//For Hammers this should be set to how long it takes to fully extend or retract
	//For Flippers this should be set to the minimum time between attempting to flip
	weaponRecharge = .5
