Fair point. I'm sorry about that. So, explanation: In Starfinder, certain characters have a "Trick attack". This is a special attack which replaces your normal attack. You perform a special check (Which is what I'm looking for) and if that succeeds, it deals extra damage plus adds a modifier to the foe. In my characters case, the check is "Acrobatics skill + d20 > 20+ the creatures "Challenge Rating" (Essentially the creatures' level). If I can do that, then the trick succeeds, I.E. my character bounced around like a monkey and startled the monster and thus dealt bonus damage (And the monster is flat-footed for the round). There are a lot of fixed numbers in this. The "20" seems to be fixed, and my character's Acrobatics skill is totally fixed. Really the only variables are the creature's CR number, which our GM tells us at the beginning of the fight and the d20 roll. So, in the end it all boils down to: d20+(Acrobatics) vs 20+ (Challenge Rating). Is the first one bigger? Then deal 7d4 damage. Otherwise we don't need to worry about it. (I'll just click on the normal attack button). When I ran a search, I got a lot of really cool and awesome responses here in the forum for this very specific thing, but they had all kinds of options in it which, though totes amazing, that just made it too hard for me to grasp the code enough to edit. It was things like (Check character's name) + (Check Character's level) + (Find the creature on the board) + (Add the creatures challenge rating from that template) + (Something about the floor) + (Give the player the choice to choose between acrobatics, bluff and stealth skills) + (Ask for their grandmothers' social security number) + 2d6 - 2d8 + 3d5 - 234 + (the date you got married).... You get the idea... I could see that there were a TON of options in the code.... And since that has to be in code, it looks like (((({{{{[[[[[2d6+{}[][][GSS#+]]] Beep +(Married)+ (Orange Juice)- 234}}}}]]]]))) And I can't tell what parts I can remove and what parts I can't... I know just enough about coding to sort of see what I need to do... but I haven't coded in a long time, so it's murky... much like the Oracle said about my future in programming... So my thought was if I simplified the question and took out all of the options... I just need to figure out how to take Ady's skill (22) and add 1d20 and check to see if it's greater than 20 + whatever the number is from the GM (I'll type it in). If so, roll the attack of the gun plus the trick attack (7d4) and say something clever. If not, it's cool, the system can just do nothing. I'll just click on my normal attack button. For the most part, during the game, we have three characters that can do this, so the GM is used to saying "You see a huge monster... its CR is 9" because he knows we are going to all trick attack it. So all I need is a prompt asking what the GM told us the CR is and then the math can go happily about its mathy business. I figured out the prompt part ( ?{Target CR|0}+20 ) and I figured out the other part ( d20+@{Acrobatics} ), I am even willing to let that be a whole number ( d20+22 ) but I just don't know how to pull off the next step. That's where the code gets weird on everyone's example. I know just putting "?{Target CR|0}+20 < d20+22, "Ady jumps into action and does " 7d4 " worth of damage, and the target is flat-footed!",null." won't work (It doesn't even respond when I click the attack button on my character sheet), so I need one more step here. I see code for other things here that uses "<" (Someone else posted a D&D Attack that was "[[{{1d20+?{Attack|0}}>?{AC|10}}*2d8]]" so I know that logical test can be used... I just don't know the actual syntax for that phrase and I mangled the one above so badly enough trying to modify it that Roll20 just stared at me like I was an alien... I also have no idea the syntax for printing to the box so I can write clever lines about how awesome my character is... I mean... that's important...just sayin'.... So...I just tried something else: I added an Attack on my character sheet, and named it "Trick Attack". In the "Attack Roll" box, I put " +16>{?{CR|0}+20} " (its 16 because it always adds my BAB, so I have to subtract my BAB from the Acrobatics 22), and then I put "7d4" in the damage roll box... It did prompt me for a CR, which is awesome! but then it always gives me a damage (even when I give 140 as a CR... which should be an absolute "fail")... and it gives me weird numbers... like "35"... which doesn't actually tell me if the trick worked or not. So I'm getting there... but I can tell it'll take days to get this right if I don't ask folks who have a lot more skill in this for help. I'm hoping this is all making some sense. I am having cat trouble (Nothing bad, our kitten is clashing with the old cat... on my forehead... all night...) and so I'm running on low sleep and my mind is not at its absolute best...
