【basic】Make a 2D Platform Game by Bolt

Fox Kin 4 years ago updated by BW3D Game Studios 1 month ago 8

As an normal girl just learning Unity and Bolt

I'll write a  basic way of making a 2D Platform Game ,by Bolt

I believe:“Learning by Doing”


  1. Title and Start

Bolt Version:
Unity Version:
Scripting Backend:
.NET Version (API Compatibility Level):

Hi Fox. Ok, you write the tutorial and I'll turn it into a video tutorial.

Thats also for me learning by doing.

Look forward to it!



  • Know how to use unity panel
  • Simple understanding of the unity ApI ,basic meaning of scripts command
  • Keep your basic logic clear
  • Introduce the introduction of the bolt


  • We are game maker ,not professional programmer
  • just you can smooth make game  ,That's enough!
  • dont be afraid of complexity ,we can continue to optimize logic

  • I will not use state machine, only with flow machine
  • I will follow my own production ideas to write tutorials, not like the traditional procedural thinking,
  • My English is not very well,  so you konw…………

1 STEP :  show logo

flow machine  in   ugui/panel   

flow machine  in   logo   which  have  animation clip

2 STEP :  flash text

state machine in  ugui/text


3 STEP :  input 

4 STEP :  go to next scene

flow machine in main camera


5 STEP :  loading

flow machine in main camera  at loading scene(1)

6 STEP :  Player control   (  walk  and  jump) 

flow machine  in player obj

move like this  (move input,face,animation)

jump like this  (jump input,animation state)

Is “in the ground ”

super unit in player obj

7 STEP:camera control 

flow machine in  main camera

8 STEP :  trigger event   ( eat coin)

super unit in  player ob

9 STEP :  collision event   ( bump block ,  random block coin )

normal block 

super unit in player obj

random coin block 

super unit in player obj

10 STEP :  collision event   ( kill enemy )

super unit in player obj

11  STEP :  update score  and  Time change———————————————————————————————————————

flow machine in  point text  

custom event a

custom event b

time change

flow machine in  time text  



I finish the game already,just by bolt ,even not type a code

Bolt is  Excellent tool! Wait more  functions or unit ,Make the flow more convenient

(If you have any questions or any suggestions, please leave a message,thanks so much!!

lets us  ”learning by doing“!)


Because I have no much time to write tutorial

so,I decided to post  each flow graph  or state graph,as the tutorial

I think there will be better flow if we optimize

learn by doing!

Great Job Fox Kim. Keep it up. 

Its finish ! 

Thanks for this, but I am having a real hard time trying to read the flow, as some of the pictures are poor quality. You should post the pictures separately and not joined together. Because when you click a picture it shows the whole thing very small. And what are the inputs in English?

Could you load your pics to a dropbox maybe or something similar?

Geez Man!

Did you get sorted out... Am also battling to see the later ones posted... Did she box drop you anything?
