I’ve looked through the documents, tried Google and everything in between… I’m pretty sure I missed it but here goes…
Other then flipbook, which is nice and easy to use, but it’s very limited in how you can animate in 2D.
For example, in Unity, I can animate a sprite like we do here in flipbook, but I can also add other sprites (children to the parent one) to the animation, I can animate position change, rotation, enabling/disabling collisions. I can pretty much animate anything that is attached to the parent sprite. I can even tell it to access a certain function of a script attached to the parent at any frame needed.
Is there a way of doing this and what are my other options in UE4?
You can use 3d programs like blender or tools like algodoo (there you can easily create animations + then you can take a picture of those frames) Or just modify the sprites in photoshop or gimp (depending on the complexity of the painting it is a really easy to create/paint animations)
The problem with those solutions is that it will add more art as far as animating a button for example. But what if I want to swing a wrecking ball. His this just done in code only or are there any way of doing this as an animation without a rig since this is a 2D game on mobile (needs to be size friendly!)
