Basalt Hit Effects

Basalt Hit Effects is a set of 12 impact and effect sprites drawn in the low-poly style, where the silhouette is an angular polygon and the face is split into flat triangles. It contains a hit spark and a critical burst, an impact ring and a ground shockwave, a slash arc, a glow orb and a sparkle, a heal mark and a shield bubble and a dust puff, a lightning bolt and rising embers.

Every other kit in this catalogue draws the interface. None of them draw the moment one thing hits another, which is the first thing a combat system needs and the last thing a solo developer gets to. An effect sprite also has no outline to hide behind: it lives on top of the game for a few frames and then it is gone.

Four triangles meet off-centre and each carries its own flat tone, which is exactly how a faceted mesh shades. There are no curves anywhere in the kit and no gradient on any facet.

Inside that style this is the Basalt reading of it: a dark interface on a ash grey palette with magma orange accents, built around a single bordered frame, square-cornered buttons at 120x44, banded bars divided into 7 segments, and solid icons on a 24px 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.

Every sprite is centred in a square canvas and symmetric about that centre, so the engine only has to scale and fade — an effect anchored off-centre drifts sideways as it grows, and that reads as a bug rather than a burst. The bodies are single-colour with no outline, because an outlined spark reads as a piece of interface rather than as light. The glow orb is built from stacked discs at falling opacity rather than a blur filter: a filter is rasterised differently across engines and turns to mush at 4x.

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 Basalt family, which means this kit and the Basalt panel kit line up without either being resized. A good fit for low-poly games.
