Expression Error

[NatXotic]

Hi there,

i'm playing with expressions a bit and i stumbled over an error in one of my expressions.

"Unable to evaluate expression -(Syntax Error - extra tokens detected in expression)"

I checked the number of arguments in my expression call and the defined expression and they are the same number.

I checked the namings in the expression and i couldn't find an error.

So where exactly do i have to look for that error?

Thx, any help is appreciated.

it would really help to find a page that describes all the common error messages

the 'extra tokens' thingy is usually because you have something in ' ' or " " that shouldn't be...at least that's what happens to me...

can you post the expression? I'll be it's something really simple that you're just not seeing

Yeah, it must be something very simple:

float doorswing(float radius, float positionX, float positionZ, float thickness, float hengeDoor)
{
    float angleDoor = 0;
    float disHBall = sqrt(pow(positionX,2) + pow(positionZ,2));
    float decVar = sqrt(pow((hengeDoor-positionZ),2) + pow((radius+thickness),2));
    float alpha = asin((radius+thickness)/disHBall);
    float beta = asin(positionX/disHBall);
    if (disHBall <= decVar, angleDoor=(alpha+beta), 0)
    return angleDoor;
}

My eyes are weiry! -lol

BTW, i know it's not the best naming, but should work anyhow, don't you think so?

The error is with your if-statement. Inside a custom expression you write them like you would do in C. It should look like:

if(disHBall <= decVar)
       angleDoor=(alpha+beta);

ah, alright.

didn't know that.

Even better.

Thx
