Can we do a shake effect?

[alex285]

Is possible to create a shake effect from the transformation node, without manually keyframe everything?

Yes:

Time --> Math(Multiply) --> Trigonometry(Sin) --> Math(Multiply)  <-- Value(Vector 2D(y))
 |                                                     ↓
 |                                                Math (Addition) --> Transform(Positon)
 |                                                     ↑
  -----> Math(Multiply) --> Trigonometry(Sin) --> Math(Multiply)  <--  Value(Vector 2D(x))

The multiplies are for speed control, the vectors for amplitude. One for x, one for y. You can replace the sin function by a more complex one e.g. for more randomness or fade in/out.

is that even close? :/

Yes, you just need to disconnect shape from time and connect it to the texture from transform.

Oh and you need the sin function to become one value of the multiplication and not to enable it. You really don't need to turn off a any node in this use case. Just make sure all of them are statically enabled.
