the title is a bit misleading but i dont know what else to say, im trying to store classes in an array to call back and spawn the entity stored in it.

 

here is what i mean:

for(int i = 0; i <= MoChickens.eggNum; i++) {
            	System.out.println("Class  " + MoChickens.egg[i] + " has been added");
            	Class<? extends Class> type = MoChickens.egg[i];
            	type chicken = new type(par2EntityPlayer.worldObj);
        	}

 

the array is egg[] which stores a class. so I want to get the spawning class from that array, but I am not sure how.

You are close :)

 

try something like:

 

for(int i = 0; i <= MoChickens.eggNum; i++) {

            System.out.println("Class  " + MoChickens.egg + " has been added");

            Class<? extends Class> type = MoChickens.egg;

            Entity newEntity = type.getDeclaredConstructor(World.class).newInstnance(par2EntityPlayer.worldObj);

//you will need to surround this with try/catch, as the reflection method can/will throw multiple instantiation exceptions

        }

Entity newEntity = type.getDeclaredConstructor(World.class).newInstance(par2EntityPlayer.worldObj);

 

it gives an error saying that newEntity has to be changed to Class and not Entity.

(Slight difference in the kind of entity, but I had a similar section of code already open)

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

when i cast to Entity i get the errors

"- Syntax error, insert ";" to complete LocalVariableDeclarationStatement"

and

"- Syntax error on token "=", Expression expected after this token"

 

here is the newer line with the cast

Entity newEntity = [Entity] type.getDeclaredConstructor(World.class).newInstance(par2EntityPlayer.worldObj);

 

and heres the updated for loop:

                for(int i = 0; i <= MoChickens.eggNum; i++) {
            	System.out.println("Class  " + MoChickens.egg[i] + " has been added");
            	Class<? extends Class> type = MoChickens.egg[i];
            	Entity newEntity = [Entity] type.getDeclaredConstructor(World.class).newInstance(par2EntityPlayer.worldObj);
        	}

whoops my bad, using the correct cast it says "Cannot cast from capture#1-of ? extends Class to Entity"

Learn about generics.

Class<? extends Class>

is not what you want.

 

I did figure that out after a while of reading the error message. I have since got what i was trying to do working. Thank you guys for your help.
