    Wanted to use sliders on one of the interfaces i was making and the existing release of sliders that i found used several unnecessary things and the code for interfaces that used sliders was all stuck into 1 method, so i decided to write my own much cleaner version.

    Create a new class called WidgetSlider
    Code:
    /**
     * @Author Suic
     * Created on 9/9/2020
     */
    public class WidgetSlider {
    
        private float minValue, maxValue, value;
        private int sliderWidth;
        private SimpleImage background, handle;
    
    
        public WidgetSlider(int minValue, int maxValue, int defaultValue, SimpleImage background, SimpleImage handle) {
            this.minValue = minValue;
            this.maxValue = maxValue;
            this.value = defaultValue;
            this.background = background;
            this.handle = handle;
            this.sliderWidth = background.width;
        }
    
        public void render(int x, int y) {
            background.drawSprite(x, y);
            int handleX = (int) MathUtils.map(value, minValue, maxValue, 0, sliderWidth - (handle.width / 2f));
            handle.drawSprite(x + handleX, y - 1);
        }
    
        public void handleSlider(int x) {
            value = MathUtils.map(x, 0, sliderWidth - 1, minValue, maxValue); // mapping to sliderWidth - 1 because x goes from 0 to width - 1
        }
    
        public float getValue() {
            return value;
        }
    }
    map method:
    Code:
    public static float map(float value, float istart, float istop, float ostart, float ostop) {
            return ostart + (ostop - ostart) * ((value - istart) / (istop - istart));
        }
    in Widget/RSInterface:
    Code:
        public WidgetSlider widgetSlider;
    
        public static void addSlider(int id, int minValue, int maxValue, int defaultValue, int backgroundSprite, int handleSprite) {
            Widget widget = addInterface(id);
            SimpleImage background = Client.spriteCache.get(backgroundSprite);
            SimpleImage handle = Client.spriteCache.get(handleSprite);
            widget.widgetSlider = new WidgetSlider(minValue, maxValue, defaultValue, background, handle);
            widget.width = background.width;
            widget.height = background.height;
            widget.type = TYPE_SLIDER;
        }
    in buildInterfaceMenu inside where it iterates thru each component

    Code:
    if (child.type == Widget.TYPE_SLIDER && mousePressed) {
                        if (mouseX >= childX && mouseY >= childY
                            && mouseX < childX + child.width && mouseY < childY + child.height) {
                            int xPos = mouseX - childX;
                            child.widgetSlider.handleSlider(xPos);
                        }
                    }
    in drawInterface inside where it iterates thru each component
    Code:
    } else if (child.type == Widget.TYPE_SLIDER) {
                        WidgetSlider widgetSlider = child.widgetSlider;
                        widgetSlider.render(child_x_in_bounds, child_y_in_bounds);
    Usage:
    Code:
    addSlider(id, 10, 75, 10, 615, 606);
    Example of it used on a interface(i know that the slider sprites don't fit the interface, only used it for testing):

    Nice interface though

    Consider using static factory method over constructor i.e

    Code:
    public static WidgetSlider createSlider(int min, int max, int default, SimpleImage background, SimpleImage handle) {
    	return new WidgetSlider(min, max, default, background, handle);
    }
    And making widget slider private

    Code:
     
    private WidgetSlider slider;
    
    slider = WidgetSlider.createSlider(...);
    
    widget.setSlider(slider);

    thanks, could you explain why i should use a static factory method over constructor in this case? i did some quick research on it but still not 100% certain whether i understood it correctly or not

    1. Flexibility, say you wanted a method where you wanted to create WidgetSlider but without a default (maybe it is 0) you can name a static factory method whereas you cannot name a constructor.

    2. Access, you can keep the WidgetSlider constructor private for encapsulation purposes

    3. If you only needed to use a single instance of WidgetSlider you could use a singleton to limit object creation to only one particular WidgetSlider instance, this will reduce the need to create an object everytime the method is called since it can reuse the same instance.

    hmm, i don't think in this case a factory method gives me any adventage here, afaik in general they're used when the creation is complex, has defaults or i can give it a better name, also imo patching fields is bad(modifying the fields directly outside the constructor/an instance method) eg in the createSlider() method:
    Code:
    widgetSlider.minValue = minValue;
    I think better than a factory method would be a Builder but that sounds like overkill to me in this scenario.
    correct me if im wrong on something tho, i just based this reply off some research
