Laser Cool Down

This is going to limit the rate of laserfire for the player.

Declare two serialized private floats:

And we’re using Time.time to limit it — that is, “the time in seconds since the start of the application” (Unity Documentation Time.time).

Below is how to include it in the code in the player script:

Time.time — the number of seconds the game is active — must exceed -1f — which is always true because time does not travel backward.

So now the code that runs when this is true has -1f equaling the number of seconds of activity added to .5f which allows the player to fire one shot every half a second.

I honestly don’t understand the math on this one, I just know it works.

CODE CLEAN-UP

Now let’s optimise our code a bit.

Under the CaculateMovement function in the player script, let’s make one just for laserfire:

And then its own void — void fireLaser():
