passing in a class and then instantiating later?

endershadow · April 12, 2013

If I wanted to accept a class in the constructor of a custom bow, and then instantiate it. How would I go about doing that. any help would be appreciated.

RANKSHANK · April 12, 2013

start with something like

public Class<? extends BowType.class> type;
public itemConstructor(int id, Class<? extends BowType.class> c){
super(i);
type = c;
}

;

then depending on if the class constructor needs parameters

public BowType bowInit(){
try{
//no parameters
return type.newInstance();
} catch(Exception e){
e.printStackTrace();
}
return null;
}

or

public BowType bowInit(){
try{
return type.getConstructor(Parameter1.class, Parameter2.class).newInstance(parameter1Object, parameter2Object);
} catch(Exception e){
e.printStackTrace();
}
return null;
}

I did what you said but it crashed on the onPlayerStoppedUsing method. Here's the code for the class file. And please ignore the badly named variables. I basically copied the ItemBow class.

There is a difference between float and Float. Read up java boxing.

what did do you mean? isn't Float the class, and float the number

then how to I make it accept a float?
