fixing switch case errors

Questions & Answers

Hi
I’m new to coding and I’m doing Walker Boys Mario Clone 2D Lab 4 tutorial and although I’m doing the exact things in the videos, I’m getting errors that i could fix.

in the enemyGumba script, everything was working well until when I added the switch ( gumbaState ) case, i start to get these errors

Assets/2D Mario Assets/Scripts/enemyGumba.js(87,13): BCE0043: Unexpected token: else.
Assets/2D Mario Assets/Scripts/enemyGumba.js(90,13): BCE0044: expecting }, found ‘case’.
Assets/2D Mario Assets/Scripts/enemyGumba.js(90,37): BCE0043: Unexpected token: :.
Assets/2D Mario Assets/Scripts/enemyGumba.js(90,38): UCE0001: ‘;’ expected. Insert a semicolon at the end.
Assets/2D Mario Assets/Scripts/enemyGumba.js(96,13): BCE0044: expecting }, found ‘case’.
Assets/2D Mario Assets/Scripts/enemyGumba.js(96,38): BCE0043: Unexpected token: :.
Assets/2D Mario Assets/Scripts/enemyGumba.js(96,39): UCE0001: ‘;’ expected. Insert a semicolon at the end.
Assets/2D Mario Assets/Scripts/enemyGumba.js(102,13): BCE0044: expecting EOF, found ‘case’.

when i identify the gumbaState, the errors reduced to the these 3:

Assets/2D Mario Assets/Scripts/enemyGumba.js(37,11): BCE0044: expecting (, found ‘Start’.
Assets/2D Mario Assets/Scripts/enemyGumba.js(37,16): UCE0001: ‘;’ expected. Insert a semicolon at the end.
Assets/2D Mario Assets/Scripts/enemyGumba.js(37,17): BCE0044: expecting EOF, found ‘(’.

here is the script

In addition to ‘infiniBuzz’ comment, you must initialize ‘gumbaState’ var in start function like this:

function  Start ()
{
   myTransform = transform.position;
  //new initializing here
   gumbaState = GumbaState.moveLeft;
  //new initializing here
   resetMoveSpeed = moveSpeed;
   linkToPlayerProperties = GetComponent ( playerProperties );
   controller = GetComponent ( CharacterController );
   aniPlay = GetComponent ( aniSprite );
 
 
}
