Editing Scratch

{{codepointer|description=Parameterized melee monster attack. Useful for custom damage values, unlike codepointers like [[SargAttack]] which act similarly but with fixed damage formulae.
|usage=
*'''misc1''' = (if ''Args0'' = '''usemisc1''') Amount of damage to inflict (default of 0 = 0) 
*'''misc2''' = Mnemonic of sound to play (default of '''null''' = no sound will be played) 
*''Args0'' = Special mode toggle (default of 0 = 0) 
**0 or '''usemisc1''' = Compatibility mode (Use value in "Unknown 1") 
**1 or '''usedamage''' = Use object damage field 
**2 or '''usecounter''' = Use value in counter specified in ''Args1'' 
**3 or '''useconstant''' = Use constant value specified in ''Args1''
*''Args1'' = (if ''Args0'' = '''useconstant''') constant value or (if ''Args0'' = '''usecounter''') counter number, 0 to 7, holding the value
*''Args2'' = Mnemonic of sound to play (default of '''null''' = no sound will be played). Used if misc2 is left '''null'''. This way you can call A_Scratch without using the '''misc''' parameters, which allows typing the codepointer in parenthesis notation or in Decorate heredocs.
*''Args3'' = Reference to a [[damagetype]], either by a string referring to the damagetype's key, or by an int referring to the damagetype's ''num'' property.
|notes=
If the object's target is valid and is within melee range (64 units), it will damage the target for the indicated amount. If the '''misc2''' parameter is non-zero and is a valid sound name, the indicated sound will played along with the attack.

Parameters Args0 and Args1 allow getting a damage value from other sources. If Args0 is '''usedamage''', the object's damage value will be used. If Args0 is '''usecounter''', the value of the counter specified in Args1 will be used. Finally, if Args0 is '''useconstant''', it will use the constant value in Args1. This has a similar effect to using '''usemisc1''' and the '''misc1''' parameter, but without the side effects caused by the "misc" parameters. When Args0 = '''usecounter''' and the state is combined with others that use [[SetCounter]] or [[CounterOp]], this allows you to perform your own custom damage calculations. The Args0 default value is '''usemisc1''', ensuring compatibility with MBF.

-For an imp-like scratch (with the same damage as that of an imp), you can use [[CounterDiceRoll]] to get similar randomness, as follows:
- IMP2 G 0 A_CounterDiceRoll(0, 3, 8, 0, assign, multiplyone)
- IMP2 G 6 A_Scratch(usecounter, 0, claw)
