![]() Wiggle( time,time ) applied to the position, means that the frequency and amplitude will increase over time, frame by frame, creating an earthquake effect. Y ou can also use expressions inside expressions: Adding the time expression to the opacity for example, modifies this property as the footage plays, frame by frame. T he time expression just expresses the time in seconds. For example, we can write an expression for position using the index: ,position,index*5] which means that x and y are normal, and then the z position is controlled by the index times 5. It's good for creating 3d ensembles and patterns. I f you duplicate the layer, it creates a duplicate in z space. For example, we can write an expression for position using the index: ,position,index*5] which means that x and y are normal, and then the z positionis controlled by the index times 5. If the layer is moved at the bottom, then the value would be the number of this last layer. ![]() ![]() If the number of the layer is 3, then the index expressions added on a property of that layer returns avalue of 3. The index expression just gives you the number of the layer. ![]() The random expression generates random values, like for example random(0,720), which randomizes the property of the layer (position, scale, rotation etc) between 0 and 720 every single frame. There are a lot of other useful expressions that we could use to make work a lot easier, such as the random, the index, and the time expressions.
