IF, THEN, =, statements

[KingKong]

How do you use simple statements like IF, THEN, =, in flash? Also how do you use variables.
for example how would I do this in flash: IF A = 5 THEN...

Hi,

Flash uses an "if/else" method instead of if/then. The format looks like this...


if(some condition == true){
do something;
}

adding an else statement .....


if(some condition == true){
do something;
}else if(some other condition== true){
do something else;
}


So, Your demo would look like...


if(A==5){
execute code here;
}else{
execute some other code;
}


Now, without going too deeply into methods without confusion, I will simply mention that there is also a shorthand for if/else statements, known as "nested conditionals". Basically shorthand for the code samples posted above...

condition ? statement : alternative statement;

A==5 ? trace("A is 5") : trace("A is not 5");


Hope it helps

Can you have an if statement within an if statement?
e.g. if (condition) {if (another condition) {do something} }
the point is to have two conditions. Is there and AND statement?
e.g. IF A=1 AND B=5 or if (a = 1) and (b = 2) {do something}

Hi,

Yes, you can nest if statements within other if statements. One problem I notice is how your using the = sign. A single equals sign(=) assigns a value. A double equal sign(==) compares a value.


if(a==1 && b==5){
do something;
}


The above requires both conditions to be true before firing the code.



if(a==1){
if(b==2){
do something;
}
}


The above is a nested if statement. The first condition must be true or the second if statement wont fire.
