i think your choons would be better if you took some more risks with your compositions and maybe alienated some people with bland tastes

you really don't need a book

literally every command is on this page: http://arduino.cc/en/Reference/HomePage

and the same site has everything you need to know about the ide (the program you code in is called the ide)

yeah but id like the coherence of a book that goes from soup to nuts and has projects and prewritten code and parts lists and stuff. and that particular book covers making your own pid controller, which is what i need for the sous vide thing (and, in fact, a yosvape) anyway. elektor guides are meant to be very good and detailed.

but you can't copypaste the code from a piece of paper! you will regret this!!!

i did a really simple 3d random walk thing that looks kinda cool
http://jsfiddle.net/x84T7/1/embedded/result/

i just made it walk in a sphere instead for fun and jesus christ math is a nightmare in js

code:

if(Math.pow(x,2) + Math.pow(y,2) + Math.pow(z,2) > Math.pow(size2,2)) {
  x = size2 * x / Math.sqrt(Math.pow(x,2) + Math.pow(y,2) + Math.pow(z,2))  
  y = size2 * y / Math.sqrt(Math.pow(x,2) + Math.pow(y,2) + Math.pow(z,2))  
  z = size2 * z / Math.sqrt(Math.pow(x,2) + Math.pow(y,2) + Math.pow(z,2))  
}

why in gods name are you not using a vector maths library

code:
if (v.modulus > size2)
{
    v = size2 * v.normalized
}

have you not come across vector maths or linear algebra before? cause if you plan on doing a fair bit of work involvin well, objects in space, it's hella useful.

best self-teachin resource is stroud's Engineering Mathematics, on account of it also being the best all-round maths textbook ever written.

i'm actually an engineer (which is why my code was so balls) so i use that stuff all the time, its real cool that there is a library for it though

edit: that book is loving amazing. that's like 36 credit hours of math in one tome!

it would be neat to train a neural network (or some other thing with an organic model not based on actual music notation rules) to trigger based on the incoming notation image and then you could physically mess up the visual signal in meatspace and make probably cool noise

its not like a complicated programming thing or anything, you just manually copy-paste the values into a vector and then use the vector instead of using a function

make sure all of those variables are the same type

for an arduino i think they should all be unsigned long

you dont need to project your childhood insecurities onto my code!


word is that I am mean to put L at the end of long variables?

its related to that but it happens at the beginning when you declare those three variables

when you declare t and risedelay and delayinjection you just say

code:
unsigned long t;
unsigned long risedelay;
unsigned long delayinjection;
otherwise really weird stuff happens when you try to add millis() to a normal int or whatever number you are using right now

took some "not-mushr00ms" the other day and spent a while wondering abott he point of spending time making gfames. at the time it seemed lieka total waste of time but now idk. i nean. ami ever going to amke money from these ? i doubt more than a little bit of spare change. certainly not career chganing. i mean even at optimal making games isnt good money unless youre very lucky AND talented. also, is it in genral a good thing to spend tiome on? aS A HOBBY IS IT ANY GOOD? IDK? its productive in a general sense but not in a real sense. am i ashamed to tell people i spend my spare time making a game? perhaps. whats the point of life? is it a waste of time? and if so, should i drop $135nzd on susbtance designer when textures arent even part of my game workflow? i guiess that answers my question but i still want it... HMMMMMMMMM

its easy to focus on the fact that its a net loss in kiwi moonbux but theres a lot of unquantifiable benefits like being a cool rear end gamedev dad and doing good posts on ironic internet forums though
