   Crafting formula
  Hi all,I have a crafting system that I am implementing into a game.I have calculated the rate at which a skill can increase, but am having problems with the formula for determining if a crafting attempt is successful or not.I am hoping that someone here might be able to help me out with this.Here is what I have come up with as a base to work off of:A crafting attempt success or failure is determined by a calculation between intelligence, wisdom, their perspective bonuses, current skill knowledge, and the trivial stage of the item being crafted.The int and wis plus their bonuses can be a value betwween 3 and 50.3 is the worst and will have the least chance of success while 50 is the best and have the highest chance of success.The players crafting skill can be between 2 and 250. 2 is the least amount of knowledge in the skill and 250 is the highest knowledge of the skill.Items will have a trivial value. it can be anywhere from 15 to 275.A person with int and wis of around 13 each, will have a 26 for the int/wis value. A person with two 18' would have a int/wis value of 50.if a person is crafting something that they have already made trivial, then they will have a higher success rate. If they are crafting something out of their range, then their success rate will be lower.A person with crafting skill of 18 and trying to create item of skill 250 should have a 2% success rate. A person with crafting skill of 250 and trying to create item of skill 18 should have a 98% success rate. A person with crafting skill of 100 and trying to create item of skill 100 should have a 70% success rate.These values are not set in stone, so feel free to play with them and see what you can get.Any and all help is greatly appreciated here, and i hope to hear your comments and thoughts.Thanks for the input and help[Edited by - razzles on September 3, 2007 11:35:45 PM]
  Questions:A person with crafting skill of 2 and trying to create item of skill 15 should have what % success rate?will a person with crafting skill of 2 and trying to create item of skill 275 have 0% success rate?will a person with crafting skill of 250 and trying to create item of skill 15 have 100% success rate?A person with crafting skill of 15 and trying to create item of skill 15 should have what % success rate?A person with crafting skill of 250 and trying to create item of skill 250 should have what % success rate?A person with crafting skill of 250 and trying to create item of skill 275 should have what % success rate?etc.   ;  Please disregard this post.I have recently been enlightened by a new type of crafting system and am no longer in need of this information. Sorry for any who investigated this.[Edited by - razzles on September 4, 2007 1:14:25 PM];  Even with you wanting me to disregard I will still post just in case you decide to fall back to your older idea. This setup gets close to what you wanted with minimal math but is still a bit off. It is just to give you a starting point foundation to then fudge from there.a = your skillb = item skillc = max(a, b)x = a/cy = b/clow = 70 * xhigh = low + 30percent = ((low - high) * y) + highi = intw = wism = max int + wisfinal = ((i + w)/m) * percentAnd just out of curiosity what crafting system have you moved onto?   ;  well I had gone to a crafting system where everything depended on what the character did. IF the fire was too low or too hot, when the materials were put in ....Turns out though that it is to complex a system for me to implement though.So i have reverted back to this system.I was able to work out a system for the crafting, and will compare some results with your system. Whichever is giving me the best results, I will post it here for others to see.Should be up later this evening.   ;  Here is the formula I had come up with. I have been busy and have not been able to do calculations to see which is better yet.(50 + ((INT + WIS) / 2) + (WIS Bonus + INT Bonus) + ((Skill Level – Trivial) / 4)
