Skeletal Mesh

Could someone help me animate a skeleton of a paragon character to walk normal and make a state machine with idle without the gun then passes with a gun?
I am very grateful to anyone who can help me.

You are kind of ordering a big deal here if you are basically asking someone to help you make the entire animation and blueprint for you. Answerhub is best suited for specific issues.

However, if you want help I will put some links to a playlist below that will help you understand and learn animation and how to set them up -

Follow this tutorial, twist and turn it to your needs and if you have an issue while doing this ask here. Best of luck!

thank you.
