--- Quote from: Howard_Casto on February 07, 2013, 09:48:17 pm ---If there was a way, I'm sure the modern arcades would be doing it. Sega still releases shooters to the arcade regularly and they have completely switched over to IR guns so they can offer different monitor options. Their rigs cost a small fortune, so I doubt they'd skimp. --- End quote --- Thats not true, nor is it good logic. One of the reasons why, may in fact be that the needed white flash, is the real issue. And or the fact that nobody really put a lot of thought and effort into it. Which in such a fast paced corporate red-tape business.. is pretty much standard operation. If you want to test pixel accuracy, then do just that. Make a set of static targets all over the screen, that are pixels, or small bulls-eyes. When the gun is fired, have it draw a different colored pixel where it landed. Have another test, where you try to fire in the exact same spot for 20 shots. Have it cycle the colors, so you can tell where each shot landed. Furthermore, Duckhunt isnt a test. Try Shooting Gallery for the Sega Master System. A few superior game, requiring far superior accuracy. |

ugh man, that was my nice answer because I knew you would start. Technical answer: 1. Lcds don't draw the screen one pixel at a time, they have buffers. At their slowest they draw a single line at a time. So no x-tracking. There's also this wierd method of interlaced redraw that's used on some lcds. (Not true interlacing... but rather first the odd pixels are re-drawn for the next frame, then the even, to speed up the refresh rate.) 2. Lcds don't have a standard refresh rate like crts did. So you'd have to build a gun for 60hz, 100 and 120hz. That's not a huge issue, but it means your gun needs three chips or a varible timing chip, which adds to the expense. 3. A lcd monitor doesn't give off enough incandescent light to trip a light sensor. Yes they could use a more powerful sensor, but it'd have to be so powerful to detect the white on a lcd that it'd often be thrown off by light around the room. Upon working on this solution they tried a camera, same issues in regards to sensitivity. Then somebody had the bright idea to put a ir filter on the camera and put tracking dots around the screen. The ir-gun ws born. I'm sure shooting gallery has smaller targets, but seeing as how nobody cares about that game I don't see how it would matter. Most people want to play the modern lightgun games (area 51, virtua cop, ect) and the targets on those games are huge and don't move around a lot. The ducks in duckhunt are tiny and irratic by comparison. As soon as crts went by the way-side I did extensive research on this and continue to do so. I've even been actively working with the community to find solutions. Trust me, a true lightgun or any mutation of one is not the solution. Could you please be nice this time and just let this one go? |

A sort of virtual CRT simulation. Once calibrated.. does not the drawing timing (freq) stay constant for a typical CRT? Is it not possible to time virtual electron drawing (without actually drawing) to a certain sized LCD? --- Quote ---2. Lcds don't have a standard refresh rate like crts did.

Costs of such things is probably under a dollar. Even if it costs 20$, people would pay for the accuracy. A gun with crappy accuracy, isnt worth anything to me, Which is why I, and many others, keep our console systems. But as said, this isnt to do with Hz. This is something that could be done programatically.. I think. Which could mean that anything that uses it, would have to use a certain programmed tracking to utilize it. --- Quote ---Upon working on this solution they tried a camera, same issues in regards to sensitivity.

An interesting idea. There are other systems they mention as well. --- Quote ---I'm sure shooting gallery has smaller targets, but seeing as how nobody cares about that game I don't see how it would matter.

(as well as time crisis) While yes, there are a lot of larger targets in these games.. there are times when you have to avoid shooting a target thats in front of another. (or a target just barely behind something else, as in timecrisis.. and yeah, PB targets move all over the place) I believe there are high accuracy shots in PB too. In fact, I believe Shooting Gallery is the precursor, and inspiration, for Point Blank. It uses the same kind of level challenge system. However, the levels are longer in SG, and the game just feels much better as a result. PB is a little too 'ADD' for me... though, it does have some cool and fun levels. SG could have easily been a top earner arcade machine. Its probably the best, most fun, and most challenging lightgun game, that Ive ever played, hands down. --- Quote ---As soon as crts went by the way-side I did extensive research on this and continue to do so.

And that me bringing up my opinion, is 'starting'.. as if Im trying to pick some sort of fight? On the Outrun board, you even went so far as to say I was angry... and yet, I had no anger, nor used anger in my replies. Its you who is putting a negative spin on things, not me. And I have a right to an opinion... even if you do not agree with it. |

Guys stop fighting! Question for the EMS Top Gun 3, there are a couple of reviews where the gun doesn't function properly(1/2 star reviews) or the batteries overheat and melt the battery cover(2 star review). Has anyone experienced this problem and if so would you still reccommend i get it? I added mouse support to my game based on: --- Quote ---All pc-based lightguns show up as either a mouse, or a joystick. That makes for easy interfacing. --- End quote --- Seeing as i can't afford a lightgun right now, should i just declare light gun support untested? Any assistance in this matter would be greatly appreciated. Sincerely, Quacker Blaster |

I am using an EMS III gun. Once I got the unsigned driver issue figured out (For Windows 7 64bit), and Ramjet's border fix installed for the model 2 emulator, it has been working great. I wouldn't say it is perfect, but it is working well for me right now. I may try a better gun later, but I am happy with the EMS right now. The only thing I really don't like about it is that it is difficult to press the buttons to disable the recoil correctly (for me anyway). |
