Hi.
2 things.
1 add force is for 3D

use add force 2D
2 Enable sequence on the state or do add force in the next state.
To set 'Enable Sequence' right click on a empty space in the action section and select.
you will now see a v form in the lines between the actions.
What this does is:
when enabled it will wait for each action to finish before going to the next action.
when disabled it will start each action but will not wait until it finishes.
