Adapt the closest official particle example with `find-examples`, prefer the\nEngine's built-in particle component over a hand-written system, and discover any shipped trail or\neffect script with `reuse-scripts`.\n\nCopy particle curve construction from the installed example exactly. `CurveSet` takes one key array\nper channel, such as `new CurveSet([0, x0, 1, x1], [0, y0, 1, y1], [0, z0, 1,\nz1])`; do not flatten three channels into one array. A malformed curve can type-check and then fail\ninside the particle texture upload. Create one emitter, render a frame, and require empty runtime\nand console diagnostics before reusing the helper for smoke, spray, or splashes.\n\nFor a polished wake, smoke, or spray requirement, do not stop at scaled planes, crossed billboards,\nor generic render primitives. Use the built-in particle component for smoke and spray; reserve a\ncustom mesh and material for a continuously sampled wake ribbon. Verify tint and blending against\nthe actual scene lighting and surface.\n\n## Place and layer\n\n- Place an effect at the emitter's world mount point; parent it there or copy the world transform once.\n- Keep additive or transparent effects above the surface they sit on and biased toward the camera so\n  they do not z-fight. Inspect soft transparency at grazing angles for hard edges, black quads, or\n  dropout.\n- Size and orient effects from the emitter's calibrated bounds, not a guessed constant.\n\n## Pool and prewarm\n\n- Create emitters, ribbons, flashes, materials, and meshes at load. Events check out an effect, set\n  its transform, and call `particlesystem.reset()` then `play()`; after its particles finish, call\n  `stop()` and return it to the pool.\n- First-use shader compilation can stall a frame. Before gameplay, render every material and particle\n  variant through the relevant passes, on an offscreen rig or behind the ready overlay.\n- Pulse or tint uniforms with `meshInstance.setParameter` or `material.setParameter`.\n  `material.update()` marks the whole material dirty and clears variants when defines or chunks\n  change; reserve it for material changes that require it.\n\n## Moving trails\n\n- Treat built-in render primitives as blocking geometry for soft effects. Follow the closest\n  official example to choose particles, a custom mesh, textures, materials, and blending for the\n  intended visual behavior.\n- Match every custom mesh's vertex streams to its material. A lit `StandardMaterial` needs normals;\n  calculate and set them before `mesh.update()`, or deliberately use an unlit material. Treat a\n  missing vertex-attribute diagnostic as a rendering failure even when some frames still appear.\n  For a dynamic horizontal ribbon created with `setVertexStream`, allocate a normal array alongside\n  positions, fill every vertex with `(0, 1, 0)`, and upload it as `SEMANTIC_NORMAL` before the first\n  `update()`. Recheck this whenever changing the ribbon's material type.\n- Never attach an empty dynamic mesh to an enabled render component. Upload a valid initial vertex\n  and index set before creating its `MeshInstance`, or keep the render entity disabled until the\n  first complete update. On reset, disable it or restore valid seed geometry; do not call\n  `mesh.clear()` while an enabled renderer still references it. Reflection and refraction cameras\n  render the same mesh and can expose this lifecycle bug before the gameplay camera does.\n- Judge a trail from its intended cameras. If it reads as a flat decal, use the reference example to\n  add the minimum depth cue needed rather than stacking arbitrary geometry.\n- Sample the trail continuously. Append segments on a small time- or distance-step and interpolate\n  between them; coarse per-distance chunks make the trail stutter and break into visible dashes as\n  the object speeds up.\n- Anchor it to the mover's contact or exhaust point, scale emission rate and length with speed, and\n  fade the tail so it dissolves instead of cutting off with a hard edge.\n\n## Camera shake and hit feedback\n\n- Drive camera shake as a decaying offset on a camera parent or an additive layer; never write it\n  into the smoothed chase position, or it fights the follow. Keep shake and follow separate, as the\n  orbit-camera rule in `apply-conventions` requires.\n- Stagger the parts of a compound effect over a few frames — flash, then smoke, then splash — so an\n  event reads as a sequence rather than a single pop.\n- Keep the readable peak long enough for the gameplay camera to see the layers together. A flash can\n  be brief, but the longer-lived layers should overlap for several frames rather than leaving the\n  primary action frame visually identical to the idle state.\n- For side-mounted emitters, derive every spawn point and direction from calibrated world-space\n  mounts on the mover. Confirm the effect starts outside the source geometry from both sides; an\n  active cooldown with only a tiny flash elsewhere in the frame is failed feedback.\n\n## Prove it fires\n\nTrigger each effect through real gameplay input and confirm with a screenshot captured at its peak,\nnot a saved filepath. Confirm the effect is visible from the gameplay camera and from a grazing\nangle, that repeated events leave entity counts stable, and that nothing leaves a black quad or a\nhard edge over the surface. Compare `graphicsDevice.shaders.length` after prewarming and after the\nfirst real event; growth indicates a missed variant. Use two fixed poses and return screenshots at\naccept-or-reject points only, not after every edit.\n\nChoose the authoring surface with the `build-app` skill; create effects through its entity and\ncomponent primitives and own their lifecycle in the surface that spawned them.\n","tagline":"Use when adding transient visual effects or trails to a PlayCanvas app to select an Engine-native implementation, place and layer it correctly, manage its lifecycle, and verify the rendered result.","category":"design-creative","commerce":{"type":"unknown","billing":"unknown","amount":null,"currency":null,"sourceUrl":null,"checkedAt":null,"runtime":"unknown","purchaseUrl":null,"checkout":"external","purchaseRequiresUserConsent":true},"tags":["agent-skill"],"author":"playcanvas","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"playcanvas/skills","creatorName":"playcanvas","creatorUrl":"https://github.com/playcanvas","sourceUrl":"https://github.com/playcanvas/skills/tree/main/skills/add-effects","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/playcanvas-add-effects#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
