Scratch

Gonna work on rewriting the touching function today in school because the coordinate system changed to be like Scratch.

Gonna finish the timed say/think functions. :3

Hey, the timer can be done with the millis function:

int timer = 0, lastReset = 0;
//stuff
timer = (millis()/100f)-lastReset;
//more stuff
void resetTimer {
  lastReset = millis();
}

Oh, and alpha:
Before you display an image, use tint(255,ghost); . You can use that for the color effect too:

colorMode(HSB,100,100,100); //set color mode to hue-sat-bri
//Bla bla bla bla
void display() {
  tint(colorEffect,satEffect,briEffect,ghostEffect);
  image(my_image,x,y);
}

I compiled it, but it didn't work

Nice code.

I know very, very, little about Processing but could you not use Scratch's sound library?

We're probably going to be using SoundCipher for the note blocks, which uses MIDI that is similar, if not the same as, Scratch's.

Thanks for the code. 
Is there any specific name you'd like to be credit as.

No, really just copy and paste. That code took me like five entire seconds to write. 

I feel dumb, cause it wasn't working for me when I tried to make one. >.>

What is "Processing?"
What would someone benefit from those two steps in the middle (between scratch and java)?

Processing is a very visual Java-based language that is pretty much a simplified Java. Going on this path would help Scratchers learn Java, because Scratch blocks are functions in Simplicity, so it would be a natural progression. Once a user gets better at understanding these, they could move on to more advanced built-in functions of Processing. And eventually, they may want even more advanced things and move into Java, which has the same syntax as Processing.

What constitutes "visual" because I tried Processing and all I got was colored text commands.

I'm still working on this by the way although very slowly.

You could try clicking Profile -> Show all posts, which is what I use. It only shows threads you've posted on, though.

What's the error?

No error. When I run it (I've tried compiling into many different formats) I just get a window of about 20x20 or something. Greyish background.

Oh. That's what's supposed to happen. You haven't written any code yet! Try this for a guide to starting out and then you can try and understand the available functions from the Simplicity source.

Wow!  It looks great!  1230 lines of code!  I was browsing through your source and wanted to ask a few things:

First of all, I noticed that the "Timer()" function returns an integer.  You might want to change it to return a floating-point value (maybe rounded to 2 or 3 decimals). 

I was looking at the "Join(String sval, String sval2)" function.  Does Processing not have a string concatenation function?  Can't you just do the following?  It looks so much like C# that I wasn't sure. 

Code:

string s1 = "Hello, ";
string s2 = "world!";
string s3 = s1 + s2;

Another thing: Are you intending to start indexing strings at 0, or 1?  So, does the statement

[str(val.value.charAt(loc))]

return the first letter of the string when loc = 0 or loc = 1?

The "toBoolean" function seems to interpret 1, true, True, and TRUE as true, but everything else as false.  Should it specifically use 0, false, False, and FALSE?  Or even throw an exception if you pass an invalid argument? 

Finally, are all sprites represented by rectangular areas on the screen (no transparent pixels)?

Thanks,

Thanks for your interest! I've been working on this for a few months now, and glad to see people like you give comments about it. 

1. I will do that. I just directly copy and pasted code on here without really modifying it too much for that.
2. There is a built in string concatenation function, but I'm trying to make this as easy for beginners as possible so I'm using the function name from Scratch. It would also be difficult for someone starting out to have two different functions, + and Join(), for the different datatypes, string and Variable.
3. loc = 0
4. I personally think, based on the current casting Scratch has, that this is how it would be done if it were possible in Scratch.
5. You may have transparent pixels but I haven't finished doing the collision for such images.
