Can a libGDX app work on multiple devices?
Getting user input from multiple devices can be tricky- a desktop application is different from a mobile app, which is different from a game embedded in a website. Luckily, libGDX exposes an API that generalizes to different devices. Most of the functions will work on every platform.
Which is better touchdown or touch in libGDX?
The touchDown event on the other hand is much more straight forward. It can be a bit confusing handling “mouse” events called “touches”, but it makes sense. Generally the logic you handle for both would be exactly the same, so no sense treating them differently.
How to move the jet in libGDX 4?
If it doesn’t work in an frame, click here. Just use the left and right arrows to move the jet. Hold down control to move slowly. There is no clipping so the sprite can fly way off screen. In terms of what the new code is doing, the Sprite.translateX method is pretty self explanatory.
What does gdx.input.iskeypressed.w mean?
For example Gdx.input.isKeyPressed (Input.Keys.W) checks whether the W key is currently pressed. This function only makes sense on devices that have a physical keyboard. This code shows a circle that can be moved by clicking or touching the screen or by pressing the WASD keys on a physical keyboard.
First, our sprites coordinate is relative to it’s bottom left corner. so if we want to center the sprite, we need to take half the sprites width and height into consideration. The next complication comes from the fact that LibGDX sets the origin at the bottom left corner, but mouse positions are relative to the top left corner.
