How to replace Shape with an image ? PShape to PImage

carolina_moreira · April 15, 2021, 4:09pm

I am trying to exchange all forms for images

What is the correct way to do it?

The game opens and no error appears
The image just does not appear when I press the Y key

hope someone can help me
thank you in advance

Hi @carolina_moreira ,

The first thing that strikes me by looking at your code is the amount of lines and repetition. And you might know that programmers don’t like to repeat themselves

You can see that there’s a pattern here :

int aa =0;
PShape aaa;

int bb=0;
PShape bbb;

int cc=0;
PShape ccc;

// ...

You are defining at least 26 separate variables that are corresponding to a letter. But you do it by hand and twice for the integer and the shape. It also implies that you need to make the conditions the same way… This is not easy to understand and debug and it’s doesn’t make your life easy.

There’s better ways to handle this like using arrays or objects.

But my question is why do you use createShape to draw basic shapes like rect, arc or triangle where you can use basic functions in Processing?

carolina_moreira · April 16, 2021, 11:06am

Thank you very much for the tips

I’m sorry I’m a beginner working with Processing so I don’t understand much yet.

What other processing functions can I use to draw basic shapes like the arc rectangle and triangles ?

The Sketch looks beautiful with the segments! A Snake of Art, or an Art Snake.

It’s y for ON and Y for OFF I think.

What to do

First, to load an image is hard for the Computer. So please use loadImage() only once in setup():

yyy = loadImage("caixa3.png");

Make sure the image is in your folder. Otherwise you get an red error in the Console Window.

you can also use resize() here to make the image smaller

yyy.resize(60, 0); // The 0 means keep aspect ratio

Second, the issue is that you don’t display the image yyy:

in function segment()

if (yy==1) {
    // yyy = loadImage("caixa3.png");
    // shape(yyy);
    image(yyy, 0, 0);
  }

No problem, everyone was here at some point

A good place to start is the Processing reference, it got all the functions and keywords you can use in Processing :

You can then check the 2D Primitives section :

Have fun
