Double-click on Packt_Animator from the
Project panel to open the Animator panel in Unity. If you messed up a little with it, delete anything except the default Idle node.
- Create three new empty states by right-clicking anywhere in the Animator window, then select Create State and Empty, as shown in the following screenshot. Name them runRight, runLeft, Idle and Jump.
- Add the run animation clip to both runRight and runLeft states, as shown in the following screenshot:
- Lastly, add the jump_pose clip to the Jump state. Here's a screenshot, just in case:
- Now we can take care of the transitions. First of all we need two variables: a float called fSpeed to check whether we should trigger the left or the right sided running animation, and a Boolean called bJump for jumping. You should remember how to do this. The following screenshot shows what you are searching for:
- Create a new transition from Idle to runRight, and in the Inspector panel, set the condition to fSpeed greater than
0.2, as shown in the following screenshot:
- We also need to create a transition back from runRight to Idle and set the condition for triggering the transition as follows: we trigger the animation when the fSpeed parameter has a value below
0.2. Check the following screenshot to be sure you are doing things right:
- Repeat the same operation with Idle and runLeft, but this time the enter condition is that fSpeed is less than
-0.2, while the exit condition is that fSpeed is greater than-0.2.
The reason for this is that when the character runs left, it is going towards negative values on the x axis and thus we need to check for negative values of fSpeed!
- For the Jump animation, we use the bJump parameter. Create a transition from Idle to Jump and set bJump to true as its entering condition, as shown in the following screenshot:
- As for the exit transition, create a new one back from Jump to Idle and set bJump to false as its condition. You can refer to the following screenshot:
- Repeat the same operations connecting runRight and runLeft to Jump to complete the task.
