Sandbox Modals

Sandbox Modals is a set of 15 modal dialogs and system notices drawn in the voxel style, where each surface is the front face of a cube with a lit top face and a shaded right face. It contains three modal dialogs at rising severity, three system plates and three system banners, a three-button footer row, a close button, a layered backdrop scrim and a plain, a focused and an error input field.

A modal is not a panel: it stops the game, waits for an answer, and sometimes the answer cannot be undone. The usual way to say that is a red border, which collides with the health colour already on screen and disappears the moment a developer retints the kit to their own palette.

The extrusion is real geometry rather than a shadow: the light angle never changes, there are exactly three tones per block, and the front face is inset so the cube stays inside its own sprite bounds.

Inside that style this is the Sandbox reading of it: a light interface on a desert tan palette with sky blue accents, built around a header band across the top of the frame, chamfered buttons at 112x40, banded bars divided into 12 segments, and two-tone icons on a 16px grid. Those measurements are why two families can share an art style without being interchangeable: the style decides how an edge is drawn, the numbers decide what the interface is for.

Severity is carried by the thickness of the strip along the top edge rather than by its hue, three pixels for a notice, six for a warning and ten for something destructive, so it survives any tint and any greyscale screenshot. The button positions are fixed and deliberate: cancel sits left and raised, the committing action sits right and recessed. That ordering becomes muscle memory across a game, and a kit that varies it is how a player deletes a save by reflex. The scrim is four stacked steps rather than one even wash, because a single black sheet over the whole screen kills the art it is dimming.

Every sprite ships as an editable SVG and as transparent PNG at 1x, 2x and 4x, so you can drop the PNGs straight into an engine or open the vector and change a colour. Built to the same measurements as the rest of the Sandbox family, which means this kit and the Sandbox panel kit line up without either being resized. A good fit for voxel and blocky games.
