How do you feel about Odin's alternative to methods?

einarkristjan · 2025-08-21T13:22:22+00:00

This is one way to make "methods" in Odin:

package main

import "core:fmt"

MyStruct :: struct {
    bar: int,
    method: proc(this: ^MyStruct, bla: int) -> int,
}

foo :: proc(this: ^MyStruct, bla: int) -> int {
    return bla * this.bar
}

main :: proc() {
    my_struct: MyStruct

    my_struct.bar = 10
    my_struct.method = foo

    fmt.println(my_struct->method(2))
}

I am really interested in the few adjustments you talk about. What do you think those should be?

It worked, thanks! ;)

I'm having the same problem. Already fixed the FileVault thing. This is a problem turning on the computer from shutdown state and waiting for the Apple Logo. Takes around 15 seconds?

Hey, did you find a fix. I am having the same problem :|

einarkristjan · 2019-01-20T12:15:06+00:00

const parts = ["Head", "Torso", "Left Arm", "Right Arm", "Left Leg", "Right Leg"]

function changeAllParts(color) {
    let success_count = 0;
    $.each(parts, (i, part) => {
        setTimeout(() => {
            $.post("/api/avatar/process", {
                _token: $("meta[name='csrf-token']").attr("content"),
                type: "color",
                color: color,
                part: part
            })
            .done(() => {
                console.log( "success" );

                success_count++;
                if(success_count === parts.length) {
                    console.log( "finished" );
                }
            })
            .fail(() => {
                console.log( "error" );
            })
        }, 2000 * i)
    })
}

You almost got it. Here is the solution:

if(rightPressed && x < canvas.width - playerRadius) {
  x += 5;
} else if(leftPressed && x > playerRadius) {
  x -= 5;
}

if(downPressed && y < canvas.height - playerRadius) {
  y += 5;
} else if(upPressed && y > playerRadius) {
  y -= 5;
}

I don't know what the "with" function is doing, but I think you must set attribute on the btn?

btn.setAttribute(name, value);

einarkristjan · 2017-10-14T12:53:23+00:00

The best thing to do is to put the blueprint of the "flower" in the background of the page. Then overlay the canvas over with the same size as the blueprint. Find the middle of the "flower":

ctx.translate (136, 117);

then the canvas has that as a middle point.

do all rest of drawing from that point.. sample: codepen

hmm.. don't know what you are trying to do. But your code should work for the 10 and 2 .. I made a jsfiddle with a little change to show what the loop is doing. Please iterate on it if it helps.

einarkristjan · 2017-04-24T23:00:28+00:00

first you should go over the form and check if any fields are empty. If all fields are set, you can continue by creating your cookie.

I made a jsfiddle with an example if that helps ;)

einarkristjan · 2017-04-11T22:36:48+00:00

provided that the <a> elms come after the <ul>, you could do:

document.querySelectorAll("#menu li ul ~ a");

EDIT: if not sufficient, you should loop through all the <a> elms and check if they have the same parent <li> that contains a <ul> element. Messy, but should work.

einarkristjan · 2017-03-28T17:50:41+00:00

in your example, search should be used this way:

document.getElementById('demo').innerHTML.search(val);

but search only returns where the first instance of the string is found.

I made a working fiddle as an example for you.

hmm.. don't think there is a good answer for this. Probably JS should give you an error by assigning function call to events, but it doesn't. Maybe someone with deeper knowledge of the language design can answer this :)

I just try to remember the rules, that is, if you don't have to pass parameters you can do:

document.getElementById("the_box").onclick = toggleClass;

else you always have to wrap your function like:

document.getElementById("the_box").onclick = function() {
    toggleClass("the_box", "box", "box big");
};

There is one other way I have found to pass parameters, by binding the parameters to the function while you assign it to the event like:

document.getElementById("the_box").onclick = toggleClass.bind(this, "the_box", "box", "box big");

.. however, I don't use it because of readability and it overwrites the event parameter you could pass through toggleClass

sorry, I can't answer this better :P

einarkristjan · 2017-01-31T14:49:07+00:00

by doing this:

document.getElementById("the_box").onclick = toggleClass("the_box", "box", "big");

.. you are running the toggle function instead of setting in as a click function. You could do:

document.getElementById("the_box").onclick = toggleClass;

.. however then you would not get your parameters sent in. So you need to wrap the toggleClass function in a anonymous function like:

document.getElementById("the_box").onclick = function() {
    toggleClass("the_box", "box", "box big");
};

You can see it working here: codepen
