--description--
JavaScript bietet das eingebaute Dienstprogramm Math an, das eine Reihe von mathematischen Werkzeugen bietet. Eine davon ist Math.random(), die eine Zufallszahl zwischen 0 und 1 erzeugt. Eine andere ist Math.floor(), die eine gegebene Zahl auf die nächste ganze Zahl abrundet.
Mit diesen kannst du eine Zufallszahl innerhalb eines Bereichs erzeugen. Dies erzeugt zum Beispiel eine Zufallszahl zwischen 1 und 5: Math.floor(Math.random() * 5) + 1;.
Verwende diesem Muster folgend den Operator zur Addition (+), um eine zufällige Zahl zwischen 1 und dem Wert von xp zu deiner monsterHealth-Variablenänderung hinzuzufügen.
--hints--
Du solltest die gleiche monsterHealth-Zeile verwenden, die du bereits geschrieben hast.
assert.lengthOf(attack.toString().match(/monsterHealth/g), 1);
Du solltest den weapons[currentWeapon].power-Wert erhöhen.
assert.match(attack.toString(), /monsterHealth\s*-=\s*weapons\[currentWeapon\]\.power\s*\+/);
Du solltest Math.floor() verwenden.
assert.match(attack.toString(), /Math\.floor/);
Du solltest Math.random() verwenden.
assert.match(attack.toString(), /Math\.random/);
Du solltest Math.random() mit dem Wert xp multiplizieren.
assert.match(attack.toString(), /Math\.random\(\)\s*\*\s*xp/);
Du solltest Math.floor() verwenden, um das Ergebnis von Math.random() * xp abzurunden.
assert.match(attack.toString(), /Math\.floor\(\s*Math\.random\(\)\s*\*\s*xp\s*\)/);
Du solltest 1 zum Ergebnis von Math.floor() hinzufügen.
assert.match(attack.toString(), /Math\.floor\(\s*Math\.random\(\)\s*\*\s*xp\s*\)\s*\+\s*1/);
Du solltest das Ergebnis von Math.floor(Math.random() * xp) + 1 zum Ergebnis von weapons[currentWeapon].power hinzufügen.
assert.match(attack.toString(), /monsterHealth\s*-=\s*weapons\[currentWeapon\]\.power\s*\+\s*Math\.floor\(\s*Math\.random\(\)\s*\*\s*xp\s*\)\s*\+\s*1/);
