bruddog Posted September 21, 2018 Share Posted September 21, 2018 I’ll try and write a detailed post on this at some pt but there is a random aspect to a kickers accuracy. Its not a random number but the value used is based on the kicking arrow speed and cycles as the arrow moves up and down. It wont always be the same value at the same arrow location. So this could cause the arrow to be in the exact same spot and have the kick bounce in one time and bounce out or miss entirely another. Because of how the math works out a 50 kicking ability kicker in average condition will never have his accuracy modified. Roughly 70 pct of the time every other kicker will have his accuracy modified. Sometimes the modification is more extreme than others as it modifies it using the top two bits of a byte value. So there are 4 possible modifcations Top two BITS of value 00 = none 01= light 01= Major 11= Major light is about the effect of the arrow being one tick higher/lower.Major ia about 4-5 ticks higher or lower.

bruddog Posted September 22, 2018 Author Share Posted September 22, 2018 Here is a worksheet you can use to see whether a FG will go in given a given arrow location. The only cells you want to change are B2: This sets how far off from perfect your arrow is. See sheet 2 for examples. B3: This is a random modifier. Set it between 0 to 3. There is a 25% chance of each one occuring except for 50 kicking ability kickers. B5: kicker skill rating (6,13,19 etc). This will fill in how many notches the arrow can be off and sets the kickers range. FG_worksheet.xlsx Quote Link to comment Share on other sites More sharing options...
Knobbe Posted September 25, 2018 Share Posted September 25, 2018 Kicking Ability dictates how far away you can be and still be in range for a FG. It also dictates the range/speed of the arrow It doesn't dictate whether or not the FG will be good. That is dictated by a combination of distance away from the endzone, distance the arrow for the kicker is away from center, and the "random accuracy modifer". You can think of the modifier as a random chance at wind or something like that which will decrease your chances of making a FG that isn't kicked dead center. If you are dead on with a kick and the kicker is in range, it's a FG. The more you are away from dead center, the less you have a chance to make the FG depending on the distance away which is common sense. You can be very off on a 20 yard FG and make it while being slightly off on a 65 yard FG can mean a miss.

Like if you kick a 52 yard FG and you are 4 notches from center a 50 KA kicker will make it every time whereas anyone else will make it half the time. If you're talking about a 49 yard FG where you are 4 notches off, all kickers will make this all the time. There are certain scenarios where this really makes a difference. For instance a long FG where you are within 2 notches of dead center has a random accuracy modifer range of 15 yards. In other words, being 2 notches off with most kickers means that you may or may not make a 69 yard+ FG. For a 50 KA kicker, if you are 2 notches off you will make the FG every time up to 73 yards. One would have to trade off the forgiving arrow of higher KA kickers and increased kicking range vs the lack of penalty for a 50 KA when trying to value them. (One would also have to realize that the changing condition of the kicker would matter as well). I won't bother to guess at this right now so that it's not taken as gospel.

hankthetank Posted October 4, 2018 Share Posted October 4, 2018 (edited) So let me see if i got this it doesn't matter if you're on the top or bottom hash missing 1 notch up or down is the same regardless So for every other kicker besides a 50 KA in Average (So a 44 in good would still be effected by it?) a Random Number effects if a kick is good or not based on how many notches from perfect you are i think i got this My understanding for the Maximum range is that a 44 Kicker can make a kick from midfield being the Line of Scrimmage and that it went one yard per notch different. Meaning Mike Lansford in bad having a 13 KA can still make a kick if the line of scrimmage is no further than your opponents 45 and Nick Lowery in Excellent having a 94 KA can make a field goal if the line of scrimamge is no further than your own 42.

buckbbuck Posted October 6, 2018 Share Posted October 6, 2018 Is there a hack that adjusts where the COM will be willing to go for a field goal? They always seem to be willing to go for 50-60 yard kicks which seem a bit unrealistic. Basically it would be great to have a hack where you can set it so COM never tries a FG unless they are inside the 40 or some, set yardline.

bruddog Posted October 6, 2018 Author Share Posted October 6, 2018 It might be better to just make the com as accurate as a human rather than the random accuracy they have now. Quote Link to comment Share on other sites More sharing options...

bruddog Posted October 6, 2018 Author Share Posted October 6, 2018 Not really no. Most humans that actually aim it can get reasonably close. The harder thing would be too know if you have a fast lb coming in at you Quote Link to comment Share on other sites More sharing options...
fgqb#19nyj Posted October 7, 2018 Share Posted October 7, 2018 Is there a hex code setting for distance accuracy that adds an additional ten yards to fgs? Quote Link to comment Share on other sites More sharing options...
bruddog Posted October 7, 2018 Author Share Posted October 7, 2018 You want to add 10 yards to the fg distance? Quote Link to comment Share on other sites More sharing options...
fgqb#19nyj Posted October 7, 2018 Share Posted October 7, 2018 Yes. I want to add the ten for my 1970-73 Roms, where the fg posts are located in the front of the endzones. I see that there's a topic that already covers this, but it's a little vague. Hope you can help. Quote Link to comment Share on other sites More sharing options...
bruddog Posted October 7, 2018 Author Share Posted October 7, 2018 Thats already where tecmo puts the posts hence why you can kick 60 yarders with ease. Quote Link to comment Share on other sites More sharing options...
fgqb#19nyj Posted October 8, 2018 Share Posted October 8, 2018 (edited) Hmm. So there's no need, then. Thanks. Out of curiosity, does that also apply to the computer? I feel as if they're a little inconsistent...even from a short distance. I'm trying to get the game to feel and play like the original is all, but with an old style football field perspective. @#294C0. The default value is 90. I'm guessing changing this to 9A would add 10 yards? Edited October 8, 2018 by fgqb#19nyj Quote Link to comment Share on other sites More sharing options...
bruddog Posted October 8, 2018 Author Share Posted October 8, 2018 The computer is not consistent because they essentially wait a random amount of time to kick the fg so their accuracy will be random too. No each 0x08 = one yard. So adding 0x50 would add ten yards. 0x90 + 0x50 = 0xE0 Quote Link to comment Share on other sites More sharing options...
fgqb#19nyj Posted October 8, 2018 Share Posted October 8, 2018 (edited) Thanks, man. I knew the math had to be off. The guy posted that FF and a 100 ka rating would mean a fg kick at around 90 yards or so, but I couldn't understand what he meant when adding up this figure. This affects the computer and man controlled player both, correct? Edited October 8, 2018 by fgqb#19nyj Quote Link to comment Share on other sites More sharing options...
bruddog Posted October 8, 2018 Author Share Posted October 8, 2018 Yes a kicker with 100 kick rating and that value changed to FF would have a small chance at making a 90 yard field goal. I don't really feel like laying out all the math but its essentially kicker skill distance value + fixed minimum kick distance value + random kick distance value Yes, it affects both the man and the com controlled players.

adscl84 Posted January 31, 2019 Share Posted January 31, 2019 (edited) FG mechanics are the last thing I'm hoping to change in my ROMs as it's frustrating how often the COM misses what should be easy kicks. Correct me if I'm wrong on any of these points: 1. Based on the values in column AP, I understand this to mean someone with 06-13KA can have the arrow travel 14 notches in either direction, whereas the arrow for someone with 94-100KA will go only 7. 2. The random modifier dictates how far from the center the arrow starts? That is, sometimes it starts dead center, and other times it starts at the far end of the kicker's range. Or, is the modifier just saying that even though the arrow is dead center, it acts as if it's a few notches off? If I've got that stuff right, can someone please explain the following? I have code at x2A7A0 that changes the arrow speed/distance: 98908880787068605850484038302820 0C0C0B0B0A0A09090808070706060505 So the bottom line of code is the arrow distance and I changed it from a range of 7-14 to a range of 5-12 notches? I suppose I can play with the range using the table to find a happy medium for me... But, I remember there being a value that determines whether a kick is clearly good, bounces in, bounces out, or misses entirely, as illustrated in this post: I think changing the green/yellow/pink/red areas is preferred, as it allows for more customization over simply saying how far the arrow moves, but is this possible and where is the hex code? Is it possible to remove the random modifier, or is there a way to apply it to those with 50KA? I'd rather everyone have it, or no one have it. Edit: I found the hex location for the image bruddog posted in the link I included about how the arrow distance works (x294df), but I don't know if that will ultimately help me.

fgqb#19nyj Posted October 9, 2019 Share Posted October 9, 2019 Does anyone know how to edit the hex location that would make all missed field goals be placed at the 20 yard line instead of on the original line of scrimmage? I know this applies to under 20, which is already in the game, but the old rule had it beyond the 20, also. This was a rule in the NFL prior to the 1974 season and I would like to implement this code into my 70-73 roms. Thanks to anyone that could help.

bruddog Posted October 9, 2019 Author Share Posted October 9, 2019 This will skip past the yardline check and always set it to the twenty. P1 side: SET (0x24502, 0xEAEAEAEAEAEAEAEAEAEA) P2 side: SET (0x24C8A, 0xEAEAEAEAEAEAEAEAEAEA) I didn't double check this but it should work TheRaj 1 Quote Link to comment Share on other sites More sharing options...
