Hi all, Found a bug in one of my previous demos: https://www.babylonjs-playground.com/#3CPL8T#1 If we will click spacebar quickly the avatar will jump higher and higher. This happens because I drop this.jumping flag on key up event. See line 135. Actually I need to drop it when camera will be on …

Hi @splash27 , I think I had a similar issue with player camera falling off of a building. I found some suggestion about using a ray that points to -Y, and then check the distance with the first picked mesh (or you can set the length of the ray when you define it). I used and it works perfectly. Ho…

@Abdullah_Alkawatrah , Thank you! But how did you cast the ray? Did you cast a new ray each time inside onCollide event or when camera moves? Or did you create a ray once and change only it’s origin inside onCollide event or when camera moves? Or did you find a way to set camera as “parent” for …

I am not sure if the below is clear enough. I call this in the renderloop. I found using a dummy box hidden below the camera (bottomBox) as the origin of the ray easier to implement. The dummy box is updated with the camera position to create a new ray. This will actually check if the camera (botto…

@Abdullah_Alkawatrah , your solution is interesting, but it still doesn’t work good for me. https://www.babylonjs-playground.com/#WECN4N Problem 1: Actor jumps now only when I release button. Not on keydown as it was before. I had to add additional flag check (jumpBtnPressed at line 229) to fix t…

@splash27 , i am using event listeners not camera controls. I am not sure if this makes a difference, I think camera inputs are queued for processing. I am using this here: https://csserver.herokuapp.com/ . You can try to climb the ladder and see how you cannot jump midair. Use shift to jump. If you …

@splash27 , I found where i got the concept of using ray cast to detect if camera is on top of something. [image] How to detect avatar is on the ground? Questions Ok, I’ve settled with this When I walked off the car my algorithm determined that she was off the ground and …

Well, the only possible solution I found to suppress undesired double jumps is throttling of jump button presses. https://www.babylonjs-playground.com/#WECN4N#1

Hi guys! Recently, I did another playground that used simple ray-casting… so now I’m an expert. (not) :slight_smile: Splash, take a look at https://www.babylonjs-playground.com/#WECN4N#3 - lines 118-130 area. (I changed all ‘this’ to be ‘camera’… maybe wiser in this situation). :slight_smile: I…

Hi Wingnut, Your solution looks much simpler and it solves double-jump problem, but it is kind of buggy in some other places. If you will press and hold spacebar until jumping end and then release it you will jump again. That’s weird. If you will press and hold spacebar until jumping end and then…

Yep, that was me. Topic was called SSS (stop sliding on slopes) I’ve taken a break from coding for the summer, but soon I’m gonna push myself to start making NYNS for real. I’ll steam it at twitch.tv/GivoGames so I can’t watch youtube if I get frustrated.
