I need help for a jumping script maybe a tutorial

yes i did use dynamic rigidbody

ask him to help me?

because i looked at the thread but i didn’t really understand the code and i dont known how to do that kind.

Can you share your project please, then I can try to assist you.


You can try to add the code below inside the update function of your firstPersonMovement script. You can adjust the force value to get the right result.

    var force = 500;
    if (this.app.keyboard.wasPressed(pc.KEY_SPACE)) {
        this.entity.rigidbody.applyImpulse(0, force, 0);

did i add it right? @Albertos

like i said im new to coding iv’e started learning 1 week ago

You did it right. You just have to save your script to apply the changes.

i saved it but i cant jump or is my force wrong?

I see there is already a force variable defined. So we have to change the name of the variable. The current force can also a little higher I guess.

    var jumpForce = 1000;
    if (this.app.keyboard.wasPressed(pc.KEY_SPACE)) {
        this.entity.rigidbody.applyImpulse(0, jumpForce, 0);


Yes, that’s right, but I think you accidentally deleted the line below from the original script, so you need to place it back.

   var force = this.force;

ok it worked but do u know how to make it not infinite jump.

yeah i think i messed it up because its falling slowly and jumping infinintly.

There’s not really a good easy way to do this. The easiest way is to use a timer or to check the current height of your player. But both are not ideal in all situations.


A more advanced option is to use a raycast to see if it can detect ground or not.

i need help fixing the jumping mechanism i keep slowly falling and infinite jumping here is the code i used

It’s not something that can be fixed. You have to adjust the rigidbody values to get the best result. Please check my own topic about it.
