Question by Rockyblack · Dec 27, 2016 at 04:15 AM · javascriptif-statements

Why won't this variable change even when the if part is true?

This code is in the update function. I tested some stuff out and instead of -= or +=, i just did = and it worked. Is there something wrong with the code?

   if (Input.touches[0].position.x < 100) {
             xSpeed -= 0.3f;
         }else if (Input.touches[0].position.x >= 100) {
             xSpeed += 0.3f;
         }

Looks legal at a glance, but odd. What exactly is happening? Which parts do or do-not work as expected?

The "else" doesn't look technically illegal but at the very least it reduces readability:

 if (whatever) {
   // do one thing
 }
 if (something_else) {
   // do something else
 }
