Thanks very much, that was a silly mistake for me to have made, I didn't make it with up, left or down so I didn't check the code for right thoroughly enough!

As always, the help is very much appreciated.

I have been doing a bit more work on my program and I have run into a problem where I feel I am probably missing something pretty silly. The cursor moves around to select character but I am trying to add collision detection to stop the cursor moving out of bounds. I have defined the limits of where ...

Thanks very much for all the help everyone! I updated my code to reflect it and added in collision detection. I uploaded the rom and code incase this might be useful for anyone in the future.

I have more things I am going to try and add so will probably have more questions soon.

I have compiled with both using -L I must admit, I am only a very low level beginner at this so the output is pretty far over my head. I have attached both outputs as txt files though!

Thanks very much for the detailed answers! I have a follow up question, when using Code: cursorx = $02c0 ; *** Refers to RAM location $02c0 cursory = $02c1 ; *** Refers to RAM location $02c1 to declare the variables, the cursor maps to where I would like to be exactly. However when using cursorx .ds...

I am working on a little project to enter text into variables and then use that variable to generate custom text later in the game. Rather than make different topics for every issue, I thought I would make one topic if that is OK? I am using a cursor to select letters kind of like a name entry scree...

Thanks very much!

I am working on a little project where I enter text on a screen kind of like a high score entry. I am storing the letters as a variable (will use astring once I get it working) then updated the background to show what is displayed in the variable in a particular location. LDA #$20 ; set to beginning...

Thanks a lot!

I have a little rom I am making where I would like to load a screen while holding a button on the controller, if not holding a button, display a different screen. ie nothing held = load screen 0 While holding A = display screen 1 My code works! But I am fairly sure it is a bit (more likely a lot) ha...

This is an open source project which is pretty close to what you are looking for already I think?

What you want is a variable to track which step in the sine you should be using for each frame. Load that variable into X before calling the function to display the sprites. What goes into that variable is up to you, but for starters, try incrementing that variable once per frame. So sill of me. Th...

Pre-generated data table for the sine wave data (X/Y coordinate offsets or whatever you wish -- it's gonna vary depending on what you want) is, IMO, the way to do this. The manual calculate-it-yourself-through-painful(IMO)-math-in-realtime isn't worth it. Just giving my two cents. Thanks everyone f...

I am trying to get an effect with sprites moving in a sine wave pattern similar to what happens in wamma's quantumdisco brothers demo at about 1:10 https://www.youtube.com/watch?v=hhoa_K75BKI It is vaguely NSFW as there is low res naked person in the background. I ASSUME that the sprites are all gro...

I have made a simple animated spritefield using a bit of code from a friend of mine (nocarrier who used to post here) and a bit of nerdy nights code and a little bit of code I wrote myself. It has 4 different animated sprites to switch between and 4 palettes to cycle though. I know it isn't spectacu...
