How do I make my entity not "climbable"?

Help & Support
1

I have a part of a game where there are walls and no roof, but you can climb the walls, the walls are pipes and there are ridges. I am trying to make the walls not climbable.

2

By climbable I mean if I walk into it and jump I go up it, Evan after jump height.

3

You need to modify the rigidbody settings (friction and damping) of the wall and maybe the player.

4

I made the walls more, I just haven’t tried the player.

5

More what?

Modifying the rigidbody of the player has also consequences for movement.

6

I tried the players rigidbody and there was no effect besides a little resistance on climbing. Nothing on movement

7

By I made the walls more means I increased the rigid body settings

8

Also the player is dynamic and the walls are static

If you share a link of your project I can take a look.

PlayCanvas | HTML5 Game Engine you can go forward through the spinning danger sign and walk into the pipes and jump It will go up a bit, not as bad as before

The problem is different than I thought.

Your jump logic ensures that you can jump again when you hit the obstacles with the side of the player.

You can give the obstacles a tag and ignore collision with the obstacles in your jump script.

Jump.prototype.onCollisionStart = function(result) { 
    if (result.other.rigidbody && !result.other.tags.has('obstacle')) { 
        this.canJump = true;
    }
};

I used your code and rebuilt the jump script, also modified your part a bit and got this:

/* https://forum.playcanvas.com/t/help-please-i-need-a-jump-feature/15408/28
Where The Jump Code Comes From!!!
*/
var Jump = pc.createScript('Jump');
var canJump = false;

Jump.prototype.onCollisionStart = function(result) { 
    if (result.other.rigidbody && !result.other.tags.has('obstacle')) { 
        this.canJump = true;
    }
    else (canJump = false);
};
Jump.prototype.update = function(dt) {
if(this.app.keyboard.isPressed(pc.KEY_SPACE)){
if(this.canJump == true){
this.entity.applyImpulse(0,0,5);  
}
};
};

No errors but I cant jump, any ideas?

Not sure why you changed the whole script so it doesn’t work anymore?

14

Do you have any problem if the script is like below?

var Jump = pc.createScript('Jump'); 

Jump.prototype.initialize = function() { 
    this.canJump = true; 
    this.entity.collision.on("collisionstart", this.onCollisionStart, this);
    this.entity.collision.on("collisionend", this.onCollisionEnd, this); 
}; 

Jump.prototype.onCollisionStart = function(result) { 
    if (result.other.rigidbody && !result.other.tags.has('obstacle')) {
        this.canJump = true;
    }
};

Jump.prototype.onCollisionEnd = function() {
    this.canJump = false; 
};

Jump.prototype.update = function(dt) { 
    if (this.app.keyboard.isPressed(32) && this.canJump === true) { 
        this.entity.rigidbody.applyImpulse(0, 350 ,0); 
    } 
};

I remade the script because I couldn’t find where your code would fit in, also it was complex and could be simpler. Also, the script works. Thanks :smiley:

16

The code is good, but after touching a wall I cant jump for a couple of seconds, any ideas?

17

I have made a Basic Jumping example project, where I use a raycast to detect the ground instead of collision. This will probably solve all the problems of this topic. Please let me know if this works for you.

It doesn’t work, no jump, I tried increasing both jump force and sensor length

19

Nevermind, It actually jumps, I am going to test it on the walls now.

You can still climb the walls but it is harder to do so, so thanks! I think this is good! Thanks again for all your help :smiley:
