Creating an Achievement System

Hey guys,

Patrick Boelens it teaching us that taking a step in Unity can be rewarding. But this tutorial covers creating a fairly basic achievement system, and having a texture scroll in whenever the player accomplishes a goal.

Very nice, thanks for sharing!

 

Very good tutorial for achievement system Now need how to save and load from an menu the pre required trophies from in-game ,and see the unlocks on the unlocks menu for example.

 

this is the AchievemnentManagerScript:

Code (csharp):

1. //trophies Textures to unlock.
2. var firstStepTex : Texture;
3. var masterTexture : Texture;
4. //trophy booleans, unlocked.
5. private var FirstStepTake : boolean;
6. private var secondStepTake : boolean;
7. var edgeMargin;
8. ////trophy sound.
9. var TrophySound : AudioClip;
10. function Start()
11. {
12.  edgeMargin = Screen.width * .05;
13. }
14. //this is the first trophy.
15. function MasterMind()
16. {
17.  if(!secondStepTake)
18.  {
19.   unlockAchievement(masterTexture);
20.   secondStepTake = true;  
21.   audio.PlayOneShot(TrophySound);  
22.  }  
23. }
24. //this is the second trophy.
25. function playerMove()
26. {
27.  if(!FirstStepTake)
28.  {
29.   unlockAchievement(firstStepTex);
30.   FirstStepTake = true;
31.   //Debug.Log("Trophy UP;)");
32.   audio.PlayOneShot(TrophySound);  
33.  }
34. }  
35. function unlockAchievement(achievementText : Texture)
36. {
37.  var go : GameObject = new GameObject("Achievement Object");
38.  go.transform.position = Vector3(0,0,Time.time);
39.  go.transform.localScale = Vector3(0,0,0);
40.  var guitext : GUITexture = go.AddComponent(GUITexture);
41.  guitext.texture = achievementText;
42.  guitext.pixelInset.width = achievementText.width;
43.  guitext.pixelInset.height = achievementText.height;
44.  guitext.pixelInset.x = Screen.width * 1.1; //Screen.width - achievementText.width - edgeMargin;
45.  guitext.pixelInset.y = Screen.height -  achievementText.height - edgeMargin;
46.  
47.  var achievementScript : AchievementScript = go.AddComponent(AchievementScript);
48.  achievementScript.edgeMargin = edgeMargin;
49. }

this is the unlocks example:

Code (csharp):

1. var trophySystemScript : TrophyManager;
2. function OnTriggerEnter(other : Collider)
3. {
4.  if(other.gameObject.tag == "Trophy")
5.  {
6.   AchievementManagerScript.playerMove();
7.  
8.  }
9.  if(other.gameObject.tag == "Finish")
10.  {
11.   AchievementManagerScript.MasterMind();
12.  
13.  }
14. }
15.  

Happy trophies

 

the notification tutorial is great, but how do you do an achievement scene that shows locked/unlocked achievements when the notification shows in game.

p.s. when i go back to the main menu everything resets including achievement notifications, how do you change this.
