I recreated Fruit Ninja as a real 48KB NES program, fully compatible with the NES Zapper. Using 6502 assembly, I cover some solutions to the constraints of the Nintendo Entertainment System, including the limitation of 64 sprites, 4 color palettes, and background creation. Also covered is a deep dive into how the NES Zapper works and how I implement it into my program. Fruit Shinobi is available to download now to run on the NES, Famicom, or your favorite emulator.

Zap Ruder in particular is interesting as it does a real time calculation of where the zapper is looking on the screen, turning it into a fairly accurate cursor.

Really cool clone. It's like Fruit Ninja was meant to be a light gun game. One problem, as the game requires a CRT to play with an actual light gun controller, the HUD elements are too close to the edge of the screen, meaning they will be cut off on most NTSC CRTs.

@DaMu24 Жыл бұрын

Yeah, even in the original Duck Hunt, the score and ammo UI have a border and some padding from the edge around the elements. Shouldn't be too hard to do something similar for Fruit Shinobi's score and life counter.

Finally someone who ACTUALLY makes their "NES game" into a....NES game, most people just make 8-bit graphics without considering any of the limitations they had on the NES.

You can do hit detection on all fruit in 4 frames or less by using a binary search instead of a linear search. (Flashing half of the sprites at once to eliminate 50% of targets per frame, instead of eliminating 1 sprite at a time with your current linear method). You may be able to reduce this further by analysing aiming trends (spatial or temporal) and skewing the elimination percentage towards the trend, for faster average detection of hits at the cost of more flash frames to detect misses. E.g. players might aim more often at the most- or least-recently launched fruit, or fruit at the top of its arc. Check that fruit first by itself, or the top 2, then use binary search from there. If you can identify a consistent trend and predict the most likely 1 or 2 fruit targets, you can save 2 or 3 frames when your prediction is correct, at the cost of an additional frame for misses/bad predictions.

@TheBcoolGuy Жыл бұрын

We're working with a 6502 here.

@davidwalker1652 Жыл бұрын

@TheBcoolGuy Yes, i realise that. This can be done with minimal code using some simple old-school binary tricks that a 6502 will have no problem with. I started coding games on Z80 and used similar techniques for sprite sorting/priority, so it's certainly doable on 6502.

@12... Жыл бұрын

yeah i was thinking this too with 8 fruits it could be done in just 3 frames, by flashing 11110000, 11001100, 10101010 but the problem is that this would break if you hit multiple fruits at once

@flatfingertuning727 Жыл бұрын

@@12... I think a ternary search would actually be better: start with 11100000, 00011100, and 00000011, and then scan whichever individual sprites are needed after that.This would scan three frames in the no-hit case, six in the one-hit case, a maximum of nine in the two-hit case, and eleven in the three-hit case. Note that getting a trigger on 11110000 but none on 11001100 doesn't mean the third or fourth fruit was hit. It could be that one barely hit one of the first two sprites.

a 0.15 second blank is a little much for every time you fire I recommend using a system where you only check if SOMETHING was shot and if so then see what it was, adds 2 frames when you shoot something, but removes 7 when you miss

@InkboxSoftware Жыл бұрын

Your idea is good, but that feels like it would punish good players since they would hit fruit more often than miss, resulting in +2 frames more often than -7.

@DArtagnonW Жыл бұрын

@@InkboxSoftware In theory--if you had more time and memory--you could calculate fruit-overlap, build a (potentially huge) list of "strikeable" objects which are either fruit or fruit-overlaps, and then use a binary search to detect a hit. Naively, I think overlap regions grow like 2**n, so 8 fruit perfectly arranged would require as many as 255 strikables. But the binary search would cut that down to just 8 checks. Then you would benefit from fewer than 8 checks for all of the not-worst-cases.

Using a sine lookup table for gravity is an odd choice. It's more typical to use a 16 bit number for Y position, a second number for Y velocity, add Y velocity to Y position every frame, and subtract a constant gravity value from Y velocity every frame. Which produces a parabola, but doesn't require a lookup table.

You know what would be cool? If you used two gun shots like a knife. First, you select the start point, then the second point. After that an object slides from the spawn point to the target point and finds whichever fruits it hit. You could probably get a knife feeling from that. Maybe add a timer so the time between two trigger pushes is short enough.
