Time Trial

Part of the Building Real Games section of Coddy's Unity journey. Lesson 55 of 56.

A time trial across a garden. The runner starts at one end with ten seconds on the clock and has to reach the white goal at the far end, around a hedge, before the time runs out. Golden clocks on the way buy a few more seconds each. When the time is nearly gone the clock turns red; when it is gone, the track starts over. Reach the goal in time and the game moves on to the Finish scene.

Write two scripts: Runner on the runner, a CharacterController, and Race on the Race object.

Challenge

Hard

The build has two scenes, Track and Finish. On the track, the clocks are tagged Clock and the goal Goal; both are triggers.

The Inspector gives Runner speed (6), gravity (-9.81) and race (the Race script).

The project's Move action runs the runner at speed units per second: right and left along x, up and down along z. It falls with gravity and moves only with controller.Move, so the hedge stops it.
Running into a clock uses it up and gives the race its bonus. Running into the goal finishes the race.

The Inspector gives Race timeLimit (10), bonus (3) and timeText.

The time left starts at timeLimit and goes down by the real time that passes. timeText shows it with one decimal, as Time: 7.4, in white, and in red (Color.red) while less than 3 seconds are left.
Each clock adds bonus seconds.
When the time reaches 0, log Time's up! and load the track again from the start.
When the race is finished in time, log the time left, as Finished with 4.2 s left, and load the Finish scene.

Press Play and beat the clock, then Check.
