Mapper (simplifies map making)

ivantis · Post by **ivantis** » Sat May 17, 2008 3:56 am

I wrote a script in Perl that takes standard input and converts it into parts of a map to copy and paste (it mainly saves your hands typing). Download it from http://arma.ivantis.net/mapper.zip.
Note: You may have to change the first line of code to your Perl interpreter's path. Mine is /usr/bin/perl.

looks nice.

what about making it do some duty work like adding in circle walls and 3 point arks.

what kind of input does it take?

kyle: how do i do that? im not too good at maps, i just needed something to do

epsy: it takes standard input, you should run it through your command line on Mac OS X and UNIX/Linux systems, if you run windows, you will need a port of Perl, find one at cpan.org

i understood it takes it's input from the stdin, i was asking what form of input does it take? i don't get it

like, on the first thing you type wall, zone, or spawn, and it will give you directions

i don't know perl but,
for a circle you would ask for center, radius and number of points.

then you would take and make a loop start at point 0 and go all the way up to that number of points (you have to have 1 extra to close it)

in that look you add the x point and y point

x would be center_x + radius_x * cos(point*2*PI/points)
y would be center_y + radius_y * sin(point*2*PI/points)

EDIT:^^yes better formula z-man i was sleepy

what? could you dumb that down for me

To draw a circle, ask the user for the location of the center and a radius, and you can use kyle's formula to determine the points that are needed in the circle.

we can add radius_x and radius_y to make an ellipse also

formula updated

hmm... idk if perl will solve with sin and cos. what do sin and cos mean anyway? im no good at math. if they dont work in perl, maybe i should translate it to C++ or something.

They're trig functions. Perl has them, but you may need to load a math module to get them. You do in python, anyway.

ok, i tried it out and perl can handle sin and cos. how do i find where the points will be plotted with that forumla?

http://mathworld.wolfram.com/Trigonometry.html

Specifically:

Let θ be an angle measured counterclockwise from the x-axis along an arc of the circle. Then cos(θ) is the horizontal coordinate of the arc endpoint, and sin(θ) is the vertical component.
