[Help] Movement events have strange values

I got a move packet. I'm interested in the X and Y position of the player. Is there something that I have to divide them by to get it in terms of blocks on the map? The Y axis is not long enough and the X axis is too short (relative to the world.)

I'm trying to overlay them on a map, and I have to stretch the coordinates, and it's not making sense to me.

Re: [Help] Movement events have strange values

                                int x = (int)Math.Round(m.GetDouble(1) / 16);
                                int y = (int)Math.Round(m.GetDouble(2) / 16);

hope it helps.

Thanks! I did something wrong initially now it works.

Re: [Help] Movement events have strange values

                                int x = m.GetInt((1) / 16);
                                int y =m.GetInt((2) / 16);

Haven't done movement in a while, but isn't that the same thing?

Re: [Help] Movement events have strange values

int x = m.GetInt((1) / 16);
                                int y =m.GetInt((2) / 16);

I tried that before and it didnt work :/

Fix:

int x = (int)(m.GetInt(1)) / 16;
int y = (int)(m.GetInt(2)) / 16;

The values at 1 & 2 are doubles.

You have to use GetDouble and round them since they can be something like 2160.349298398 and that is not an int. unless you round it.
And dividing it by 16 gives you the block coords they're on.
The reason it's multiplied by 16 is probs the size of the smiley. since the location needs to be accurate.

Re: [Help] Movement events have strange values

Wait, why do they have to be ints? If it's just dividing by 16 which gives the right value, then m.GetDouble(1)/(double)16 would work.

Re: [Help] Movement events have strange values

Unless you want it to give you int values for the loc, then the code you posted should work except you don't need the "(double)" as 16 counts as a double, too.

Re: [Help] Movement events have strange values

To fill up DarkDragon4900's statement:

you don't need the "(double)" as 16 counts as a double, too.

Every integer can be typecasted into a double, and will be done automatically if it has to be done.
Officially 16 counts as an integer, but the compiler converts it into a double, as it notices a double is required.
And a bit quicker way (in my opinion) to covert 16 into a double would be by declaring it as such '16.0'. (When you're have an int variable you indeed would have to use '(double)[variable]')

Re: [Help] Movement events have strange values

Actually, what you should do is convert them to int first, then divide with 16.

Because dividing a double with decimals would have bad consequences.

It would return offset positions. Compare.

I added the

to indicate that it isn't a double by default :p

I guess i'd agree with this.
