Automatic jump

How can i make my animations automatic jump when the ground is higher.

 

Put a trigger on the jump spots and then call the jump animation ?

 

You could use raycasting in the walking direction and trigger the jump at a certain distance.

 

I never worked with raycasting can you give a little explanation?

I did this but it don't worked very well.

 

Sure. What you want to use is this method: http://docs.unity3d.com/ScriptReference/Physics2D.Raycast.html

It takes the origin of where you want to cast the ray and the direction. I don't have access to Unity or Visual Studio right now, so you might need to convert this pseudo-code to actual code to be used in your game.

Code (CSharp):

1. var hit = Physics2D.Raycast(transform.position, Vector3.right * direction, distanceToTriggerJump, obstacleLayerMask);
2.  
3. // If we walk toward an obstacle ...
4.  
5. if(hit.collider != null)
6. {
7. // ... and that obstacle is a staircase or whatever ...
8. var hitAbove = Physics2D.Raycast(transform.position + Vector3.up * heightOfObstacleThatStillTriggersJump, Vector3.right * direction, distanceToTriggerJump, obstacleLayerMask);
9.  
10. // .. jump
11. if(hitAbove.collider == null) Jump();
12.  
13. }

 

Thx!
