Version without titlescreen: Crash Course No Title.bin Sourcecode : Crash Course.bas

Having a small bit of trouble with my pfscores, I'm doing a silly sumo game where player 1 & 2 mash buttons and try to push each other out of the sumo ring and when a sumo is pushed outside the game pauses for 1 second, removes a pfscore block from the losing player and resets for the next round, but the pfscore just scrolls like mad when a sumo goes outside the ring, any thoughts on what I did wrong? This is the code that handles the sumo positions. When a sumo goes outside q goes from 0 to 1, locking the controls and reduces a pfscore, then goes to q=2 to stop it from the mad pfscore scrolling but it dosn't quite work. if player0x=54 then q=1 : pfscore1=pfscore1-1 : q=2 if player1x=91 then q=1: pfscore2=pfscore2-1 : q=2 if q>0 then k=k+1 if q>0 && k=60 then goto begin EDIT Silly me, I forgot it's pfscore1 = pfscore1/4....Works fine now. On a sidenote, I can't figure out how to limit the firebutton properly so the players can't hold them down?

Just a small project I made in 24 hours, I think it's pretty fun and very challenging. You drive a car on a road and try to dodge cars as you drive past them. The goal is to reach the top of the screen which will raise the difficulty making the cars go even faster. You get 3 missiles to shoot down the other cars in your way, but you only get 3 missiles, they can be refilled by reaching the top of the screen. Controls are: left and right to jump lanes, firebutton to fire your missiles, switchreset to start the game from the titlescreen, restart in the game and at the gameover screen. Hope you'll have fun with this silly title. It's main inspiration is the old Donkey.bas. DOWNLOAD - Crash Course.bin

Nevermind, the error was that I had forgotten to remove an unrelated piece of code.

Okay, I've done some animations on the cars, I added sound for when you crash, and a 2-second lockout for when the game is over, and I'm fiddling with controlled randomness, but I can't really get the desired results, any pointers on what I might be doing wrong with this code that handles the cars random positions? if player2y>180 then c=1 if c=1 then player2x=255 : player2y=255 : c=2 if c=2 then player2x=rand : player2y=0 : c=0 if c=0 && player2x<30 then c=1 if c=0 && player2x>130 then c=1

Right on, I'll make improvements in the areas you suggested, stay tuned for an upgraded version.

Neon Run is a racing game in the style of an endless runner. You drive past other cars, and try to blast them for points, the cars gets faster and after a while you begin to encounter giant oles, it's fiendeshly hard I think, but very fun. I'm no genius when it comes to sound so there's no master compositions, just the engine hummin and the sound of your neon lasers. Controls: Left/right to steer, fire button to fire the neon laser, press the reset switch at the titlescreen to start, and to restart either ingame or when you crash. NTSC: Neon Run NTSC.bin PAL: Neon Run PAL.bin Reviews & opinions are always good, aswell as feedback on what's good/bad, and if you encounter glitches. The only glitch I know of is that sometimes the cars fuse together.

Clever solution, thanks =)

Here's my second game, it's a racing game that started out as a techdemo to see what I could do with DPC+ Multisprites and I found it to be quite fun so I wanted to share it. Danger Lexicon: Neon Racer: These guys come in many colors and your goal is to drive past them or blast them for points. Pothole: Watch out, if you hit these potholes you will surely die! Neon Railing: A collision with the Neon Railing is not recommended as your atoms will be spread across the galaxy! Controls: On the titlescreen press the reset switch to start the game. Move the joystick left and right to steer your car, press the fire button to shoot neon lasers and blast the other cars for points! When the game is over press the reset switch to start over. Known glitches: Sometimes the other racers stack on top of each other looking a bit funky. What's it about? The highscore of course, my high score is 175, can you beat it? Suggestions & Honest reviews are greatly appreciated! NTSC Version: Neon Run NTSC.bin PAL Version: Neon Run PAL.bin SPECIAL THANKS TO RANDOMTERRAIN FOR ALL ASSISTANCE ON THE DPC+

Hm, I feared as much, Ah well, I can still work with color scrolling for pretty much the same effect. Thanks

Sorry for asking on the subject of DPC+ scrolling again, I don't quite get it, I can get the playfield to scroll with pfscroll 255 which makes the playfield scroll down, but it shoots down and the playfield is empty for a while before coming around, I understand this is because I haven't set a starting and ending column, and from what I've gathered this is where DF0FRACINC Playfield Data comes in? Anyway, my question would be, how would I need to formulate a code for the playfield to scroll down, and designate a starting and ending column?

I've experimented with collision detection on the DPC+ and for the most parts I can get it to do what I want, but now I managed to mess something up, any thoughts on this problem: The code below works perfectly, except for that player2-6x/y won't take effect, their y position won't go to 0 and their x position refuses to randomize, BUT, if I switch the order of things and put playerx=rand : playery=0 just after trick=x then it works but whatever is put last on the row of code won't work, is the code to long for the 2600 to calculate or did I miss something? ;``````````````````````````````````````````````````````````````` ; Width of sprites. ; dim enemyP2=j dim enemyP3=k dim enemyP4=l dim enemyP5=m dim enemyP6=n dim trick=o if !collision(ball,player1) then goto SKIP if (bally+4)>=player2y && bally<=(player2y+4) && ballx >=player2x && ballx <= (player2x+64) then trick=0 : score=score+5 : s=0 : player2x=rand : player2y=0 if (bally+4)>=player3y && bally<=(player3y+4) && ballx >=player3x && ballx <= (player3x+72) then trick=1 : score=score+5 : s=0 : player3x=rand : player3y=0 if (bally+4)>=player4y && bally<=(player4y+4) && ballx >=player4x && ballx <= (player4x+64) then trick=2 : score=score+5 : s=0 : player4x=rand : player4y=0 if (bally+4)>=player5y && bally<=(player5y+4) && ballx >=player5x && ballx <= (player5x+72) then trick=3 : score=score+5 : s=0 : player5x=rand : player5y=0 if (bally+4)>=player6y && bally<=(player6y+4) && ballx >=player6x && ballx <= (player6x+64) then trick=4 : score=score+5 : s=0 : player6x=rand : player6y=0 SKIP RacerTech0.5.bas EDIT: Nevermind, I found a solution, I just added in this and it works like a charm on this occasion too, sorry for being silly. if (bally+4)>=player1y && bally<=(player1y+4) && ballx >=player1x && ballx <= (player1x+64) then score=score+5 if (bally+4)>=player2y && bally<=(player2y+4) && ballx >=player2x && ballx <= (player2x+64) then score=score+5 if (bally+4)>=player3y && bally<=(player3y+4) && ballx >=player3x && ballx <= (player3x+72) then score=score+5 if (bally+4)>=player4y && bally<=(player4y+4) && ballx >=player4x && ballx <= (player4x+64) then score=score+5 if (bally+4)>=player5y && bally<=(player5y+4) && ballx >=player5x && ballx <= (player5x+72) then score=score+5 if (bally+4)>=player6y && bally<=(player6y+4) && ballx >=player6x && ballx <= (player6x+64) then score=score+5

Thank you so much, mate. Yeah, I've mixed alot of old and new code, I haven't fully made the transition over to the new stuff, old habits die hard I guess =) I'll look at your recommendations tomorrow.

Ah, sorry. Here's the .bas: Racertech.bas I double checked my variables and did some adjustments but it didn't help, seems variables being erased wasn't the issue.

I have an issue with getting my project to save highscores, I'm using RandomTerrain's "Save Highscore" example and it's self explanatory yet I can't get it to work, hm. It goes into bank3 which I set aside for when the game is over, but it won't cycle through any scores, it just shows the resent score the player got, what did I do wrong? bank 2 temp1=temp1 __Bank_2 ;*************************************************************** ;*************************************************************** ; ; Program Start/Restart ; __Start_Restart ;*************************************************************** ; ; Displays the screen to avoid going over 262 when reset. ; drawscreen ;*************************************************************** ; ; Clears the playfield. ; pfclear ;*************************************************************** ; ; Mutes volume of both sound channels. ; AUDV0 = 0 : AUDV1 = 0 ;*************************************************************** ; ; Clears all normal variables and the extra 9 (fastest way). ; a = 0 : b = 0 : c = 0 : d = 0 : e = 0 : f = 0 : g = 0 : h = 0 : i = 0 j = 0 : k = 0 : l = 0 : m = 0 : n = 0 : o = 0 : p = 0 : q = 0 : r = 0 s = 0 : t = 0 : u = 0 : v = 0 : w = 0 : x = 0 : y = 0 : z = 0 var0 = 0 : var1 = 0 : var2 = 0 : var3 = 0 : var4 = 0 var5 = 0 : var6 = 0 : var7 = 0 : var8 = 0 rem **************************************************************** rem * rem * Create aliases for variables. rem * rem * You can have more than one alias for each variable. rem * If you use different aliases for bit operations, it is rem * easier to understand and remember what they do. rem * dim Master_Counter = j dim Swap_Scores = k dim Debounce_Reset = k dim Debounce_Fire = k dim High_Score01 = l dim High_Score02 = m dim High_Score03 = n dim Store_Temp_Score01 = o dim Store_Temp_Score02 = p dim Store_Temp_Score03 = q rem **************************************************************** rem * Makes better random numbers. rem * dim rand16 = z rem **************************************************************** rem * Converts 6 digit score to 3 sets of two digits. rem * dim sc1 = score dim sc2 = score+1 dim sc3 = score+2 Master_Counter = 0 : score = 0 : Swap_Scores{2}=0 bank 3 Game_Over_Setup rem **************************************************************** rem **************************************************************** rem **************************************************************** rem **************************************************************** rem * rem * Game Over rem * rem **************************************************************** rem **************************************************************** rem **************************************************************** rem **************************************************************** rem **************************************************************** rem * Checks for a new high score. rem * if sc1 > High_Score01 then New_High_Score if sc1 < High_Score01 then Skip_High_Score rem * First byte equal.

Robotron is indeed possible on the Atari 2600, I'm working on a version with at the moment 6 enemies on screen, I'm going to bump it up to 9 when I'm done with the alpha stage.

Got it working perfectly, thank you so much.

Ahh, I'll look into that too! It's always good to look at separate things and compare for a greater understanding =)

Thanks, dude. I missed that part. I'll do some experimenting with the code tonight and see if I can get things going =)

I've figured out many things of the mysteries of DPC+ but this one I can't quite figure out. I'm having 6 enemies on screen and player0 is controlled by the player, and sprites 1-6 are the enemies. Player0 can shoot the ball as a projectice and I'm trying to figure out a good way to do collision detection between player1-6 and the ball. My question is: Do I need to put player2-6's x and y values into variables to detect a collision as with the old multisprite kernel? I atempted this code but it only works with player1, all other gives a compilation error. if collision (ball,player1) then score=score+5 : ballx=255 : bally=255 : player1x=255 : player1y=255 rem THIS GIVES COMPILATION ERROR: if collision (ball,player2) then score=score+5 : ballx=255 : bally=255 : player2x=255 : player2y=255

Thanks, works like a charm! It's hard to keep track of so many things, I'm glad you where available to help me out =)
