Java Client Applet - Passing one boolean to another

Alright, so progress is going great. I am now working on server-side picking up. That way two clients will know when someone has picked up an item off the ground.

Alright, so the tileGen inside has different booleans that tell to either draw or NOT draw the weapon or allow the weapon to be picked up.

Anyway, for now I'm working on the sword...  here is how it works.

When a client who is picking up the Item does this:

  if (drawSword)
{
	if (currentMap == 1)
	{
		if (spawnX == 13 && spawnY == 7)
		{
			drawSword = false;
			draw = "drawSword";
			currentItem = "3";
			try
			{
				addInv(3);
			}
			catch (Exception ere)
			{t
				ere.printStackTrace();
			}
		}
	}
}

Open in new window


If the drawSword is true ... then allow this. If they are on Map 1... keep allowing... if they are on the specific X and Y... then ALLOW for the pickup.. all checks are good. drawSword then turns false which is for the one time pick-up. draw is the string to be passed to the server later on. the currentItem string is the number ID of the item used to get information about it (name, desc, type of weapon, etc.), then it adds the inventory of the person who picked it up. then later on (not shown in the code above) it sets myCommand as "pickup"

Anyway, after that... on line 1023 is where it sends this action to the server:
} else if (myCommand == "pickup") {
				//int theirTile = board[spawnY][spawnX];
                  os.println(me.getUsername() + "|" + currentItem + "|" + draw + "|"+ theirTile + "|pickup");
            }

Open in new window


Their tile was going to be the tile it's under on. But then I figured out I could just set the boolean of the item so it wouldn't be draw again. So technically it doesn't matter if I sent over theirTile  but I left it there for now. The me.getUsername is the person who picked it up. the CurrentItem is the ID of the picked-up item and the draw is the string of the boolean it was picked up.

Then we go back to Line 420 where the run() is at.
 if ("pickup".equalsIgnoreCase(temp[4]))
{
	c.append("\n"+temp[0] + "|" + temp[1] + "|" + temp[2] + "|" + temp[3] + "|" + temp[4]);
	//int changeX = Integer.parseInt(temp[1]);
	//int changeY = Integer.parseInt(temp[2]);
	//board[changeY][changeX] = 4;
	int theItem = Integer.parseInt(temp[1]);
	c.append("\n"+temp[0] + " picked up a " + getItem(theItem)[0]+".");
	Boolean.parseBoolean(temp[2]) = false; // drawSword = false?
}

Open in new window

the first line is for debugging purposes. then we go to int theItem which parses the string to int which is the item ID. Then the message says "Someone picked up the some item".
Then here is where my problem lies. I'm trying to get the string "drawSword" as the boolean to be false but I get this error:

C:\wamp\www\mystikrpg\tileGen.java:428: unexpected type
required: variable
found   : value
	Boolean.parseBoolean(temp[2]) = false; // drawSword = false?
	                    ^
1 error

Tool completed with exit code 1

Open in new window


So.. close... :P

Any help?

Yes, the code doesn't make any sense. You can either get the value, or set the value:
boolean which = Boolean.parseBoolean(temp[2]);



// Or



temp[2] = "false";

When I try [b]temp[2] = "false";[/b] ... it seems to compile correctly... but I get this:

Good try though =)

Here is my new pickup...


if ("pickup".equalsIgnoreCase(temp[4]))
{
	c.append("\n"+temp[0] + "|" + temp[1] + "|" + temp[2] + "|" + temp[3] + "|" + temp[4]);
	//int changeX = Integer.parseInt(temp[1]);
	//int changeY = Integer.parseInt(temp[2]);
	//board[changeY][changeX] = 4;
	int theItem = Integer.parseInt(temp[1]);
	c.append("\n"+temp[0] + " picked up a " + getItem(theItem)[0]+".");
	boolean which = Boolean.parseBoolean(temp[2]);
	which = false;
	c.append(temp[2] + " is... " + drawSword);
}

I'm not sure what your intent is here. What are you trying to do with the boolean?

Trying to set it to false for every client.

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

I just got an idea here. Wouldn't it be easier just to handle the booleans of the items on the Server instead?

But what variable is boolean that you're referring to? What's its name?

Then why don't you just do the following?
drawSword = false;

Because then I'd have to do this...

 if ("pickup".equalsIgnoreCase(temp[4]))
{
      c.append("\n"+temp[0] + "|" + temp[1] + "|" + temp[2] + "|" + temp[3] + "|" + temp[4]);
      //int changeX = Integer.parseInt(temp[1]);
      //int changeY = Integer.parseInt(temp[2]);
      //board[changeY][changeX] = 4;
      int theItem = Integer.parseInt(temp[1]);
      pickedUp(theItem, temp[0]);
      //c.append("\n"+temp[2] + " is... " + drawSword);
}

 public void pickedUp(int e, String x) {

              if (e == 1) {
                                  drawFlail = false;
              }
              if (e == 2) {
                                  drawBattleaxe = false;
              }
              if (e == 3) {
                                  drawSword = false;
              }

              c.append("\n"+ x + " picked up a " + getItem(e)[0]+".");


        }

which WORKS! :)

But here's the problem.

Player A logs in... player B logs in. Player a sees player B take the flail on the ground. The flail is not draw on the ground anymore. But then palyer C logs in and sees the flail on the ground because his drawFlail is STILL true... get it?

This is a new Q so I'll open one up.

Thanks! :)
