is velocity max or limit or range possible?

is velocity max or limit or range possible? cuz i make my guy walk, and he just keeps gettign faster and faster

[Troodon]

if (xvelocity > 10)
{
xvelocity = 10;
}

[Fuzzy]

Code: Select all

xvelocity = xvelocity % 10;


That is all you need.

[Troodon]

Code: Select all

xvelocity = xvelocity % 10;


That is all you need.

Wow I haven't seen that used in this case before!
What's the % doing? Earlier I tought it was temporary var.

[Fuzzy]

Its the MOD operator. it divides var by 10 and chucks the quotient away and keeps the remainder. since the remainder has to be between 0 and 10, you get the range you want.

Actually I should have said

Code: Select all

xvelocity = xvelocity % 11;


If you are willing to restrict to certain values you can do it another way.

Code: Select all

xvelocity = xvelocity & 8;


1,2,4,8,16,32... is the sequence. Its even faster than %.

Interesting

Nice, here's a score.

[Fuzzy]

Thank you for the point!

[Bee-Ant]

So % and &...also...
I'll try
Btw, how long you work with code stuff Pete?

[Fuzzy]

2 days!

[Bee-Ant]

Dont make a stupid joke
Btw, do you have another idea to solve my problem in "SENIOR I NEED HELP" topic in this Game Development Sub forum???

[mrzee001]

Trying fuzzy's approach to ristrict the velocity to a certain limit,
xvelocity -= xvelocity % 11;
I keep getting an error msg : "illigal binary operation to ' % ' "
any idea why?
thanks

[Fuzzy]

its because xvelocity(and most of the actor movement variables) are real or float values. You need to type cast to an integer.

Code: Select all

xvelocity -= (int)xvelocity % 11;


should work.

Type casting means that you tell GE(or C/C++) to temporarily consider that variable to be an integer. Certain operations like % and & only work with integers.

[mrzee001]

that was the problem, so thank you for the tip.
