  • Sequencer — a timeline / curve editor for keyframe animation. See Timeline.
  • Tilemap painter — tools for brush, erase, rectangle, line, bucket, select, eyedropper, and terrain (autotile), plus stamp flip-H / flip-V / rotate-90° (H / V / R while a paint tool is active) and a random-scatter mode (D). The palette selects with the arrow keys (Shift grows a multi-tile stamp), and maps can be orthogonal, isometric, staggered, or hexagonal. See Tilemaps.
  • Tileset editor — author per-tile collision (box, circle, polygon, slope presets; one-way / sensor / material modifiers) with direct-manipulation shape editors on a magnified tile: drag a circle’s centre or radius, click-add / drag / click-delete a polygon’s vertices, and pick a one-way platform’s solid side (top / bottom / left / right) — resizing keeps the sensor / material / density modifiers. Also terrain sets for autotiling (edge/corner peering or multi-color corner Wang), per-tile probability weights and properties, and animated tiles — drag frame thumbnails to reorder, or set the whole loop to one uniform duration, with a live preview.
  • State Machine (.esfsm) and Behavior Tree (.esbt) editors — visual graphs for AI. See Gameplay AI.
  • Material Graph (.esmatgraph) — a node editor that compiles to a shader. See Materials & Shaders.

The State Machine and Behavior Tree editors share a common node canvas: middle-drag to pan, wheel to zoom toward the cursor, drag an output handle onto another node to connect them, click to select a node or edge, Delete to remove it, and right-click the canvas to add a node at the cursor.
