First time I was able to get to the invisible robot. Granted the Black and Invisible robot aren't as nasty as they are in the original game yet. Black and Invisible have bullets that can stop your bullets, and destroy your bunker. So this is not indicative of how hard it will be, but it's still pretty hard to get this far.

Still having trouble with sound effects hanging, is it something to do with sounds not using all channels playing on top you think? Seems to happen when the explosion sound plays over a laser shot, and the explosion is only using the noise channel

Updated ROM in post 1 New Sound FX! Low tone laser shots New Death Sound (also doubles as robot shield sound) Heartbeat thrump louder New Pickup and Player Spawn sounds.

I had been running into #1 recently, I'll give your work around a try, thanks!

Updated ROM in post 1 Bats and Spiders die from bullet hits from main robot Extra Man every 10000 points

Updated Rom Image in post 1 Fixed these bugs. Made some significant performance fixes. Watch video to see. FIXES: Speed of the game is too slow Robot scoring is messed up past 5000 points

Yeah, that's the line that loads the data into the VDP.

If you're running from XB you need that line, otherwise you don't need it. Are your sounds not working in just the compiled program or in XB as well. The steps I use to successfully get it working are use SLCONVERT to create the list Assemble to generate the OBJ use COMPRESS to create the VDP data to read in, set whether it's in low or high memory, it will generate the addresses for each sound. Merge the data with your XB file Read the compressed data into the VDP before playing the sounds 2810 READ A$::IF A$="" THEN 2820::CALL LINK("CWRITE",A$)::GOTO 2810 2820 RETURN Use CALL LINK("PLAY",[address#]) to play each sound in your game When you compile it should work just fine. Remember any CALL SOUND statements in your program will override anything playing on player 1 Where is it not working for you? Are you getting errors when you assemble the soundlist?

You can't have the XB256 line in when you compile

Thanks, but I'm running out of memory, so I'm ditching it for now so I can work on the gameplay, if I can get it back down I'll try to fit it in.

Updated rom image on post 1 Back to no title screen, bunker sprite is removed when the player leaves, cuts down on sprites overlapping. fixed the issue with the bats that turn into robots losing the maze path.

Your music is not using player 2 correct? Because if it is that's what causing it. If it's not any standard CALL SOUND statement will also interrupt it

Correction 32x24 color locations, 256x192 pixels

I tried replacing all values of 1-4 with variables, it made no difference once compiled as Falcon suspected.

Interesting 1st One: 2nd one: Guess it's worth taking a shot, I use values 1 thru 4 to define the different bullets and monsters, suppose I could start there and see what fruit it bares, thanks!

Excuse my ignorance here, but how does a variable holding the value of 1, take up less space than the value 1?

Updated Rom Image Find space or make new title screen Title screen is back I took the suggestion to use variable arrays for the maze constraints and intersections, and got a lot of memory back, the speed is about the same though. Senior Falcon had posted the opposite of this in some other message thread. That is why I went with using * for AND and + for OR because he said it saved a little bit of memory. Is that not right? Here's the link: http://atariage.com/forums/topic/273371-4k-shortnsweet-game-contest/page-8?do=findComment&comment=3974965

That game play looks sped up, am I crazy? Or maybe it's because I've been playing my dogsh*t slow version so much lately. :-) Thanks for the kind words shack, you've been a lot of help with the XB256 stuff

You go to sleep in this forum and the world changes a week later. Senior Falcon is the man. His new Game Dev kit, makes compiling almost a completely friction free experience.

Got it, Thanks

Video should be working now YouTube marked it private for some reason So put the sprite positions for the robots and bats in a 2 dimensional array and check against that? Is that what you guys are saying? Something like XX(ROW,COL), Storing all the the intersection locations in that to check against. Do I have that right? And would that improve speed as well?

Updated the Rom image in 1st post. Had to remove my title screen to make room, just so the game can run compiled. Will look into trying to free up memory, or just make a simple title. Bats and Spiders die from bullet hits from player Level 2+ Robots pursue player through maze Add delay before player and robot respawn Game is more or less feature complete, lots of debugging and performance issues to sort out. Level 4 robot features aren't critical as I don't think many will get there yet. Has anyone played it?

I now have level 2 or higher robots chasing the player, it's working pretty well. However, I'm running out of memory after the game is compiled, I don't know why, but I'll have to look into optimizing it. In extended basic, the memory left is roughly 4.6k remaining before I run it, and roughly 3.6k remaining after running it, so I'm not sure what's happening after compiling that's causing me to lose that 3.6k, but that doesn't seem right. because of this I have not uploaded a new rom image since it doesn't run.

Updated Rom image in Post 1: Bats and Spiders die from bullet hits from player This is the last major hurdle, but in getting this working the delay for the robot respawn seems to have broken Game is playable but too slow, I need to optimize some more, also running up against memory limits, lots of if/then statements that I'll need to see if I can do it better, Notepad ++ reports 178 IF/THEN Statements If anyone wants to take a crack at improving speed and memory, I've included the code. I program in TIdBit so the comments are in that format. Be nice, Code is not my strong suit. EDIT: Updated in a later message, just didn't want people trying to fix problems I fixed http://atariage.com/forums/topic/276268-night-stalker-in-progress-xb256-compiled/?p=3985398
