Hey there I'm using libGDX and I have following problem, just can't see what I'm doing wrong:

I have

float generatingTime = 0;

if (generatingTime < 1.0f){
   generatingTime =+ 0.01f)
   }

if (generatingTime == 1.0f){
   objectState.state = objectState.GENERATED;
   }

Somehow my float generatingTime never is exactly "1.0f". What am I doing wrong?

Thank you for helping guys!

What programming language? – Patrick Hofman Apr 22 '15 at 07:19
`=+` is obfuscating. Please put a space between the symbols. As for your question, not all numbers can be represented exactly in a `float`. Can you not scale your time unit by 100 and use an integer? – Bathsheba Apr 22 '15 at 07:19

Is the `=+` a typo? It's `+=` in the question title. – David K Apr 22 '15 at 07:20
And `0.01f)` is a typo tool I guess. Should be `0.01f;`. – Patrick Hofman Apr 22 '15 at 07:20

For that matter, how is `generatingTime` ever greater than `0.01f`? You set it to zero, then add once, then test `if (generatingTime == 1.0f)`. Maybe there are even more typos in the code? – David K Apr 22 '15 at 07:23
