Layer Automation Triggers
Creates an automated layer function based on layer ids and frame indices.
Syntax
getLayerVisibleAtTime = (id, ind) => {}
Parameters
id
A number
describing the id of the layer to show/hide. The parameter itself is not based on the index of the layer in the layer array.
index
A number
describing which frame is being checked.
Returns
A boolean
indicating whether the layer of the specified id should be visible at the specified index.
Examples
Shows layer 1 after 1 second and toggles layer 2 every 5 frames.
getLayerVisibleAtTime = (id, ind) => {
/** Boilerplate to convert layer id to index */
if (!window.idToIndex) {
window.idToIndex = []
const getSimulatorTrack = (state) => state.simulator.engine
const getTrackLayers = (state) => getSimulatorTrack(state).engine.state.layers
for (let [i, layer] of [
...getTrackLayers(window.store.getState()),
].entries()) {
window.idToIndex[layer.id] = i
}
}
id = window.idToIndex[id]
/** End of boilerplate */
if(id === 1) {
return ind > 40
}
if(id === 2) {
return ind % 10 < 5
}
return true;
