Variable Length Jumps | Coding a 2D Game Engine in Java #50

Join the Discord: / discord
In this episode I go over a method to create variable length jumps. This method involves counting a certain number of frames, and after enough frames have passed ignoring the player input if they are pressing space. If they stop pressing space early, then we stop applying a jump force. I also scale the jump force linearly so that it runs smoothly and you get the same jump every time if you supply the same input. Next, I go over how to make a block "bop" when Mario hits the bottom of it. I extend this same concept to question blocks, and finally I implement a question block that spits out a coin when Mario hits it.

This is precocious, there aren't even tutorials like this to find nowadays.
Keep it up, you deserve way more subs!

[@EdWard-cv5gc]

Looking forward to go through all theses vídeos!

[@ABHISHEKSINGH-nv1se]

I am enjoying this series. May this series keep going and keep teaching me new stuffs.
And thanks for making these awesome LWJGL videos.

[@GetRektTom]

You just gained yourself a sub. Going to watch this entire series from ep. 0 now

[@LawMasterTimmy]

thanks so much for this series so far, the only channel I can find making a 2d game engine

[@jorgeaugusto30]

Very good and informative video. Congratulations!

[@hilbert_curve3680]

Dude, great video and video series, but I kinda want to see more “How it Works” videos. All on your time, of course. Keep up the great work.

[@v_1040]

you deserve more views and subs bro.

[@GamesWithGabe]

Thanks V_ :)

```Java
// Create a new class for the jumping ability
public class PlayerJump {
// Set the maximum height of the jump
public static final int MAX_HEIGHT = 20;
// Create a method for the jumping ability
public void jump(){
// Calculate the current height of the jump
int currentHeight = 0;
while (currentHeight < MAX_HEIGHT) {
currentHeight++;
}
// Make the player jump
System.out.println("The player is now jumping!");
}
}
```
