case statement in Scripting

I am just playing around with the "case" statement. I have not used this statement before so this is my first time. And I found this statement really useful.

Anyway, I am using this script which has a case statement.

Code Snippet

Plaintext

main
{
place1 = getEnt("place1","targetname");
place1 thread place_weapons("m9");
}

place_weapons(weap)
{
ice_model = GetEnt("ice_model","targetname"); 

while(1)
{
while(isDefined(self))
	{
		players = get_players();
		for (i = 0; i < players.size; i++)
		{
		ice_model hide();
		self waittill("trigger", player);
 
		currentWeapon = players[i] GetCurrentWeapon();
		if(currentWeapon == weap)
		{
			self trigger_off();

			level.times_placed++;

			if(level.times_placed == 1)
			{
				case "m9":
				players[i] takeweapon("m9");
				ice_model show();
				ice_model setmodel("zombie_3rd_perk_bottle_doubletap");
				self waittill("trigger", player);
				players[i] giveweapon("m9_upgraded");
				ice_model hide();
				self trigger_on();
				break;
                                }
                    }
          }
}
}
}

But when I am loading my map, I get a script compile error saying, "illegal case statement". What did I do wrong with the case statement?

Thanks in advance.

case statements are only allowed within a switch block.

Uhm, a what? So what exactly is it I need to change at the case statement?

Like this:

Code Snippet

Plaintext

main
{
place1 = getEnt("place1","targetname");
place1 thread place_weapons("m9");
}

place_weapons(weap)
{
ice_model = GetEnt("ice_model","targetname"); 

while(1)
{
while(isDefined(self))
	{
		players = get_players();
		for (i = 0; i < players.size; i++)
		{
		ice_model hide();
		self waittill("trigger", player);
 
		currentWeapon = players[i] GetCurrentWeapon();
		if(currentWeapon == weap)
		{
			self trigger_off();

			level.times_placed++;

			if(level.times_placed == 1)
			{
				switch(currentweapon)
				{
					case "m9":
					players[i] takeweapon("m9");
					ice_model show();
					ice_model setmodel("zombie_3rd_perk_bottle_doubletap");
					self waittill("trigger", player);
					players[i] giveweapon("m9_upgraded");
					ice_model hide();
					self trigger_on();
					break;
                               	}
			}
                    }
          }
}
}
}

EDIT: Really i'd just suggest an if statement instead of a case statement for what your trying to do. Case statements are primarily used as a way to return values, not do lengthy code.

Okey thank you, that seems to have fixed it. Now an another error pops up. The script compile error is saying,
"missing case statement"
And developer 1 says that it is something regarding those first three lines you often have in scripts.

Code Snippet

Plaintext

#include, etc

Is it an another file I need to include there? If so which one?

No, nothing wrong with that more than likely. But make sure you add a default case statement. Most likely why that is happening is there is a value being returned that is not listed down.

this is how a case statement is setup

Code Snippet

Plaintext

var = undefined; //the variable has to be set before the actual script

switch(var){ // var is the variable
  case "1": // what the first option the variable could be

  break; // how to end a case
  
  case "2": // what the second option the variable could be

  break;
}

this is used instead of lots of if else statements. you use this when the variable is set before this script. I used undefined to show that it has to be set before.

Hmm, well I still don't know exactly what I need to do, what value?

I'm a noob.

The value of the variable you "switch over". Although that shouldn't be causing any problems, it just wouldn't execute any case at all.

Well, then I have no idea what's wrong. I don't know how I should correct the script myself. D: I can't see anything wrong with it.

Like said, it 'switches' to the value returned and executes the code. Let's say you have the case for 'm9' and 'thompson'. If you carry any other gun, presumably it'd pop out an error or do nothing. If it IS popping out an error, you have to add a default case so that if it isn't one of the listed guns it's execute the code in the default case.

Yay, I added this,

Code Snippet

Plaintext

default:

And the map loads without errors now. But when I hit the triggers, it doesn't take the weapon. (m9)

Here is the updated script if you wan tto see that.

Code Snippet

Plaintext

main
{
place1 = getEnt("place1","targetname");
place1 thread place_weapons("m9");
}

place_weapons(weap)
{
ice_model = GetEnt("ice_model","targetname"); 

while(1)
{
while(isDefined(self))
	{
		players = get_players();
		for (i = 0; i < players.size; i++)
		{
		ice_model hide();
		self waittill("trigger", player);
 
		currentWeapon = players[i] GetCurrentWeapon();
		if(currentWeapon == weap)
		{
			self trigger_off();

			level.times_placed++;

			if(level.times_placed == 1)
			{
				switch(currentweapon)
				{
					case "m9":
					players[i] takeweapon("m9");
					ice_model show();
					ice_model setmodel("zombie_3rd_perk_bottle_doubletap");
					self waittill("trigger", player);
					players[i] giveweapon("m9_upgraded");
					ice_model hide();
					self trigger_on();
					break;
                                        default:
                               	}
			}
                    }
          }
}
}
}

Thanks for the help so far, I am getting closer and closer to get it working.

Not very good at scripting, but..

You call this

Code Snippet

Plaintext

place1 thread place_weapons("m9");

But the function is this

Code Snippet

Plaintext

place_weapons(weap)

Shouldn't it be

Code Snippet

Plaintext

place1 thread place_weapons(weap);

because it switches to the m9 inside of the function itself?

Hmm, that can't be the issue as this script works in other cases. This time I am making it with the case statement, but it just doesn't takes the weapon.

Test this

Code Snippet

Plaintext

main()
{
	place1 = getEnt( "place1", "targetname" );
	place1 thread place_weapons( "m9" );
}

place_weapons( Weap )
{
	ice_model = GetEnt( "ice_model","targetname" ); 

	while( 1 )
	{
		while( isDefined( self ) )
		{
			ice_model hide();
			self waittill( "trigger", player );
 
			CurrWeap = player GetCurrentWeapon();
			if( CurrWeap == Weap )
			{
				self trigger_off();
				level.times_placed++;

				if( level.times_placed == 1 )
				{
					switch( CurrWeap )
					{
						case "m9":
							player takeweapon( CurrWeap );
							ice_model show();
							ice_model setmodel( "zombie_3rd_perk_bottle_doubletap" );
							self waittill( "trigger", player );
							player giveweapon( CurrWeap + "_upgraded" );
							ice_model hide();
							self trigger_on();
							break;

                   	    default: 
                   	    	break;
                   	}
				}            	
        	}
		}
	}
}
