Slider bar

The Slider bar object provides a simple form control allowing the user to pick a value between a minimum and maximum by moving a slider along a bar.

Slider bar control

Form controls are actual HTML elements floating above the game canvas in the HTML page. Therefore, nothing can be displayed on top of a form control, apart from other form controls.

Form controls position themselves according to the layer parallax, scale and so on. However they are not truly "in the game" (since they float above), so it is recommended to avoid using scrolling, parallax and layer scaling with form controls, otherwise the end result can feel unnatural.

Slider bar properties

Minimum
The lowest value that can be picked, when the slider is all the way to the left.
Maximum
The highest value that can be picked, when the slider is all the way to the right.
Step
The increment of possible values. For example if the step is 10, then the slider will jump in units of 10 as it is moved, and only a multiple of 10 can be chosen as a value.
Tooltip
An optional tooltip to show while hovering the mouse over the control.
Initially visibile
Whether the control is initially visible or invisible in the page.
Enabled
Whether the control is initially enabled and usable, or disabled so that it cannot be interacted with.
ID Optional
An optional id attribute for the element in the DOM (Document Object Model). This can be useful for accessing the element's value from external scripts, or styling with CSS in the HTML page.
