ActionScript 3 Error: 1180: Call to a possibly undefined method CustomClass.

ActionScript 3 Error #1180 Description:

One reason for this this error is because you are using the name of the variable that you are assigning to the Class rather than the Class itself.  Adobe also states that this error will only display when “Strict Mode” is turned on.

Flex / Flash Error #1180 Fix:

Make sure that when you instantiate the Object that you are using the Class name and not the variable name.

Bad Code:

var myCustomClass:CustomClass = new myCustomClass();

Good Code:

var myCustomClass:CustomClass = new CustomClass();

ActionScript 3 Error: 1038: Target of break statement was not found.

ActionScript 3 Error #1038 Description:
A break statement is used only with loops. They will not work in if statements. This is directly from the documentation:

Appears within a loop (for, for..in, for each..in, do..while, or while) or within a block of statements associated with a particular case in a switch statement. When used in a loop, the break statement instructs Flash to skip the rest of the loop body, stop the looping action, and execute the statement following the loop statement. When used in a switch, the break statement instructs Flash to skip the rest of the statements in that case block and jump to the first statement that follows the enclosing switch statement.

In nested loops, break only skips the rest of the immediate loop and does not break out of the entire series of nested loops. To break out of an entire series of nested loops, use label or try..catch..finally.

The break statement can have an optional label that must match an outer labeled statement. Use of a label that does not match the label of an outer statement is a syntax error. Labeled break statements can be used to break out of multiple levels of nested loop statements, switch statements, or block statements. For an example, see the entry for the label statement.

Pay attention to the last two paragraphs if you want to break all the way out of a function/method rather than just the loop that the break statement is inside then you need to use label. A very handy but seldom used method

Flex / Flash Error #1038 Fix:
Make sure that your break statement is within a valid loop such as for, while, switch statements, etc… Another alternative is to use a return statement without any parameters. Warning: Using return will break out of the function entirely and will not execute any code after the if statement. return is typically used as the last line of code in a function.

Bad Code:

if (totalScore < 10)
{
finalMsg = “Sorry!<br /> You need more practice”;
break;
}
else if (totalScore < 20)
{
finalMsg = “Congratulations!<br /> You kept yourself and others safe”;
break;
}

Good Code:

if (totalScore < 10)
{
finalMsg = “Sorry!<br /> You need more practice”;
return;
}
else if (totalScore < 20)
{
finalMsg = “Congratulations!<br /> You kept yourself and others safe”;
//break can be removed to get rid of the error;
}

ActionScript 3 Error #1061: Call to a possibly undefined method addEvent through a reference with static type flash.utils:Timer.

ActionScript 3 Error #1061 Description:
AS3 error 1061 appears when you have misspelled a property or function and have not assigned a value to it. If you haven’t properly typed the Object to begin with you will get AS3 Error 1069. See the examples below. AS3 error 1061 is actually pretty nice to work with because it tells you exactly which method/property didn’t work and it tells you which object it didn’t work on.

Flash / Flex Error 1061 Fix:
Find the object listed in the error and then check the spelling after the dot.

Bad Code 1:

var t:Timer = new Timer(1000, 60);
t.addEvent(TimerEvent.TIMER, Tick);

Good Code 1:

var t:Timer = new Timer(1000, 60);
t.addEventListener(TimerEvent.TIMER, Tick);

Related ActionScript Error(s):
Flash / Flex Error 1069 – You will get AS3 Error 1069 instead of 1061 if you don’t properly type your object before referencing a property on it. For example var t:Timer = new Timer(1000, 60);
t.addEvent(TimerEvent.TIMER, Tick); will give error 1061 but var t = new Timer(1000, 60);
t.addEvent(TimerEvent.TIMER, Tick); will give Error 1069.
Flash / Flex Error 1119 – The dreaded AS 3 Error 1119
Flash / Flex Error 1056 – This is the error you will get if you try and call a property with a misspelled name in the same way as calling a property with a misspelled name.

ActionScript 3 Warning: 1102: null used where a int value was expected.

ActionScript 3 Warning#1102 Description:
This warning is pretty good at describing what is happening but is needs to add a little to explain why. This error will appear when you try and force a variable to be a certain Type within a predefined function. For example if you have a variable like _minute below

Flex / Flash Warning1102 Fix:
Find where you are using null and make sure that you are using the proper value

Bad Code:

var TargetDate:Date = new Date(_year, _month, _date, _hour, _minute=null);

or

var TargetDate:Date = new Date(_year, _month, _date, _hour, _minute=”10″);

or

var TargetDate:Date = new Date(_year, _month, _date, _hour, _minute=false);

Good Code:

var TargetDate:Date = new Date(_year, _month, _date, _hour, _minute=10);

Warning:
You will not get this error with the code below even though it seems like the same as the code above. The smart folks at Adobe put in logic that will accommodate for numbers-as-strings and also boolean which will result in the number 0.  The AS3 Warning will will only show when you assign an non-permitted variable within the parameters of a method call. The code below will output a valid date. Direct assignment in quotes will be translated into a valid Number not an int. False shows up as 0 in the date.

var TargetDate:Date = new Date(_year, _month, _date, false, “10“);

AS3 Error 1067

Flash / Flex Error #2078: The name property of a Timeline-placed object cannot be modified.

ActionScript 3 Error #1061 Description:
The MovieClip or Button that you have on the stage cannot be changed with code. It already has a name so you can’t change it. If you are visiting this page my guess is that you are thinking that you have a dynamic movieClip that you named with code, yet you probably have one with the same name on the stage already.

Flash / Flex Error 1061 Fix:
Stop trying to change a named object on the stage that already has one.

Bad Code:

myMovieClip.name = “Bob”;

Good Code:

//no code here

Thanks and Happy Flashing
