(Dark Basic Pro) I'm making a simple 2D shooter, like Raiden or Xevious but not as fancy, and I'm stuck on left/right movement. I can use the MOVE SPRITE command to enable up/down (Y Axis) movement, but I don't see how I can move the sprite left or right without rotating it. How do you do this?

Is there some way you can use the Offset Sprite command?

i am not by a compiler now but something like this should work


If it moves too fast then lower the values that are not 0. If it goes backwards then change the negative values to positive and the positive values to negative. If any more problems exist just post

That would just change the object's postion (also, it's a sprite, not an object).

good luck

If you want a tutorial for beginners on how to move a user controlled sprite around the screen, here's a link to a series I've been working on:

use the "sprite" command each frame. The sprite command creates a sprite or moves it (depending on if it's been created already). If you still don't get it, you should familiarize yourself with variables first. You should be able to understand this code:
