Silly Problem with variables

[ElyxiaElvenbright]

I keep coming across a problem were i say:
varTotal = var1 + var2

and instead of adding them together for a combined total, its puts them gether... for example if var1 equaled 1, and var2 equaled 2, together they wouldnt equal 3, but 12... kinda anoying and im not sure what im doing wrong to make this happen...

Can anyone tell me some specifics that change how the variables hold the values? and what makes it so they no longer combine but mearly add on to other variables?

Heres the code just in case you can pick out an error that is making my code not work. Below explains the variables in question
/code
//code resides on 1st frame of main movit timeline
//start up values
_root.outputAgil = 5;
_root.outputStr = 5;
_root.outputWepSkill = 5;
_root.outputWepDam = 1.5
_root.outputLevel = 1;
//crit chart
critArray = [0,6,6.25,6.50,7,7.25,7.50,8,8,8,9,9,9,10,10,10,11, 11,12,12]

function calcStats(){
//-----CRIT CHANCE
//crit chance info
playerAgility = _root.outPutAgil;
playerLevel = _root.outputLevel;
critMod = _root.critArray[playerLevel];
critChance = playerAgility / critMod;
critChancePer = critChance * 10;
//check skills of player to mod crit chance
playerWepSkill = _root.outputWepSkill;
wepSkillMax = playerLevel * 5;
wepSkillMod = playerWepSkill / wepSkillMax;
wepSkillPer = wepSkillMod * 100;
//mod crit chance by weapon skill
critChancePer100 = critChancePer / critChancePer;
critChancePer100total = critChancePer100 * 100;
finalCritMod = critChancePer100Total / wepSkillPer;
totalCritChance = critChancePer / finalCritMod;
//send complete chance to output
_root.outputCrit = totalCritChance;
//-----ATTACK POWER
agilityMod = playerAgility / 5;
>> totalAttackPower = agilityMod + playerWepSkill ;
_root.outputAtt = totalAttackPower ;

}


/code

The problem is with the line i put the ">>" on. If i trace totalAttackPower it doesnt combine the variables together but tags on onto the other... Thats where my problem resides and i hope you can help me with =)

Hope i have been clear, and thanks in advance if you can help =)

I think you just need to convert it to a number: int(variable), Or you can get creative with using '-' instead.

varTotal = -(-var1 - var2);
or
varTotal = int(var1) + int(var2);

You can also convert it somewhere else

var1 = int(var1);
or
var1 = int(someOtherVariable);

By the way, it's doing this because it thinks that 1 or both of your variables are strings (such as 'abc') and not numbers. Also, the '+' operator is used to combine strings as well as to add numbers together so it picks which version of '+' to use, which is why '-' works because it always applies to numbers so flash converts them to numbers for you.

thank you for your reply =) helped

Though when i use int(variable) i cannot use anything besides whole numbers... so 1.2 becomes 1, and i need the ability to have fractions. Know a way to be able to define a variable as a integer but still able to hold fractions?

Thanks so much =)

Ely

edit: as a side note, some fractions get insanly long, such as 3.3333333~, know a way that it will stop after the hundredth? so it would only display 3.33? doesnt apply but i didnt want to make a new thread for justy this silly question =) thanks!!

It shouldn't do this at all. What version of AS are you using?

if you are using AS 2, you could try decaring the type of variable.

e.g

var myNumber:Number = 5

Try using Number(var1) + Number(var2)

thanks so much for the replies!!

Number(var) worked like a charm thanks =)

Not sure about what version AS im using, how would i tell? Im using FlashMX if that helps.

NEW QUESTION =)

Figure asking them here is better then new topics =)

Q: Is it possible to random a fraction? Currently my code would look like this:
Var1 = 2.6
Var2 = random(var1)+1;

var2 will random the whole number, but it will ALWAYS be .6. The .6 isnt randomized. Is there a way to do so? so that its truly random.

Thanks again for your help =)

[fil_razorback]

var1=2.6;
//Set the integer part of the random number
random1=random(Math.floor(var1))+1;
//Set the decimal part of the random number
tempvar=var1-Math.floor(var1);
random2=(random(10*tempvar)+1)/10;

final=random1+random2;

I guess this is not the best way to solve your problem but it works

[rolf_dk]

What about something like this:

var1 = 2.6;
var2 = Math.random() * var1;

This would return a number in the range 0 - 2.6. This could fx return 2.00021

OR if you only want numbers like 1.4, 3.1 etc try something like this:

var1 = 2.6;
var2 = (Math.floor(Math.random() * var1*10)/10);


BTW You are using AS1 if you got MX.
