Is it possible to do a case thing and switch in jass? For example this from c++: Code:
double getConColor(int playerlvl, int moblvl)
{
if(playerlvl + 5 <= moblvl) {
if(playerlvl + 10 <= moblvl) {
return 5;
}
else {
return 4;
}
}
else {
switch(moblvl - playerlvl)
{
case 4:
case 3:
return 3;
break;
case 2:
case 1:
case 0:
case -1:
case -2:
return 2;
break;
default:
// More adv formula for grey/green lvls:
if(playerlvl <= 5) {
return 1; //All others are green.
}
else {
if(playerlvl <= 39) {
if(moblvl <= (playerlvl - 5 - floor(playerlvl/10))) {
// Its below or equal to the 'grey level':
return 0;
}
else {
return 1;
}
}
else {
//player over lvl 39:
if(moblvl <= (playerlvl - 1 - floor(playerlvl/5))) {
return 0;
}
else {
return 1;
}
}
}
}
}
}

I'm guessing that what you want is the syntax, in which case the answer is not today. If you just want the speed of a jump table, you could use an array of triggers or strings to ExecuteFunc. But it looks like the cases you want could be written quite simply as a few if/then/else range checks... |

what does that double function mean? could you also tell me what a floor is? how could it be rewritten into jass? |

double is a type. it means real with extra precision. floor means round to the integer below. floor(1.5) = 1.0; floor(-1.5) = -2.0. Similar to R2I, except there is no conversion to an integer type. And I think R2I is trunc, where -1.5 ->-1, but don't quote me on that. Further questions would be better directed to the programming forum. |

so a floor can be:  JASS:R2I(I2R(1.5)) or would it be best to write a function for this? |

yes, that will do the job, at least for positive numbers. a separate function is not needed. I would only recommend that if we had a good way of inlining. |

You know you can put integers everywhere that it takes real arguments without problems (note: there is an exception to this, returns), so there's no need for the I2R. And what the hell is up with that piece of code Real to integer ( integer to real ( 1.5) )!! 1.5 is not an integer. Just use R2I(real) to floor a real. |

opps my bad i meant I2R(R2I(1.5)) I need to keep it as a real for the return |

Haha, that just goes to show you why automatic type casting is a NASTY bug. |
