Variables:
1.
very simple, just create variable and Debug.Log them out:
2.
The tricky part is to insert the variables as string in the story text elegantly, without using too much + operator:
therefore I use the operator in the code:
IF statement:
I combined the 3 car speed control tasks together in one program
when pressing w the car accelarates, when pressing s it decelarates
when the speed is positive the state is moving
when the speed is negative the state is reverse
when the -0.001 < speed < 0.001 speed will become 0 and state = stop
speed limited to -100 ~ 100, reaching the boundary will cause the state to become overspeed
To enable keyboard input, I used the special function in unity GetAxis()
To have a reasonable update rate of data, I used Time.deltatime
Switch
- color
Very simple, not much to say.
2. change weapon
I feel like it is easier to implemnt it usinf IF, because I googled that it is not quite easy to detect arbitary keyboard input and tell what is the key in unity.
Array
- change color
2. change color by tag
For loop
1.
I feel the most difficlut part is to put the camera at the right position so that it can see all the cubes
2.
function
I put the three tasks together：
press w to move
press space tgo change color
press s to measure distance
