Animation Player

Animation Player is a Windows tool made in Luna Mosaic for previewing and tuning 2D sprite-sheet animations.

Open a PNG, BMP, JPG, TGA, GIF, or WebP sprite sheet with the native file picker. Animation Player estimates the frame size, columns, rows, and frame count, then lets you correct every value.

Features:

• Adjustable frame width, frame height, columns, rows, frame count, playback speed, and rotation

• Inclusive loop ranges such as frames 2–6 or 5–10

• Dedicated current-frame display

• Edge padding and inter-frame gap controls

• Zoom buttons and mouse-wheel zoom

• Pause and resume with Space

The startup splash and “Made in Luna Mosaic” label identify the engine used to create it.
