Help with porting Game Maker project to Unity

So, Im trying to port a part of my game maker project to unity.

I realize that the create event, step event functions can be replaced by void start, void update in unity, but Im needing for help to "translate" the other details.

The firts I want to do, is port the player.(iM USING BOX2D)

Code (CSharp):

1. Create Event:
2.  
3. execute code:
4.  
5. /// Set Fixed rotation && Stats
6. event_inherited();
7. hp = 5;
8. spd = 0.15;
9. hspd = 0;
10. vspd = 0;
11. xaxis = 0;
12. yaxis = 0;
13. len = 0;
14. dir = 0;
15. attacked = false
16. image_speed = 0;
17. scr_get_input_player1();
18. [
19.  ///scr_get_input_player1
20. right_key = keyboard_check(ord("D"));
21. left_key = keyboard_check(ord("A"));
22. up_key = keyboard_check(ord("W"));
23. down_key = keyboard_check(ord("S"));
24. dash_key = keyboard_check_pressed(vk_space);
25. attack_key = keyboard_check_pressed(ord("E"));
26. switch_weapon = keyboard_check_pressed(vk_tab);
27. use_weapon = keyboard_check(ord("Q"));
28. start = keyboard_check_pressed(vk_escape);
29.  
30. //get the axis
31. xaxis = (right_key - left_key);
32. yaxis = (down_key - up_key);
33.  
34. //Check for gamepad input
35. if(gamepad_is_connected(0)) {
36.    gamepad_set_axis_deadzone(0, .5);
37.    xaxis = gamepad_axis_value(0, gp_axislh);

41.    switch_weapon = gamepad_button_check_pressed(0, gp_face4);

Have you taken the time to go through the videos on C# scripting in Unity (though you can use Javascript or Boo if you prefer - Javascript would be much more similar to Game Maker language)? They will answer a lot of basic questions about features that exist in Unity that are equivalents for much of what you have done in GameMaker. Key bindings and input for example are covered in video #17: GetButton and GetKey.

There are also other tutorials (such as this one) which are great for getting a basic understanding of Unity.

How familiar are you with object oriented programming, C#, or Javascript?

Please be specific with any problems you're facing, otherwise I am afraid that you won't find much help. Be specific about what you are struggling with, or what in particular you need help with.

 

Do you know how I can modify an object depth in unity(without using z)?

 

um. you should read the documentation.

Start with Input.GetKey

much of your trouble may be solved there, but you really need to get used to the unity workflow.

Good Luck

 

Sorting layers will probably be the answer you are looking for.
