How do I make a basic attack macro which checks for a hit?

Ok so essentially, I want to know how to make a basic attack macro. I can't figure out if there's any sort of "if" statements, or if there's a way to make one. Basically in my ruleset, attacking works thusly: Roll for attack on targeted enemy (easy part) Attack roll is calculated as /roll d20 + @{melee} If the attack roll is higher than {target|AC}, then I want it to roll damage dice If the attack roll is 8+ higher than {target|AC}, then I want it to roll 2 damage dice How do I make the if statements? Can i make them depend on target ac?

Macros do not have have a conditional component.  There was a suggestion  If / Then / else capability or at least score checking but it looks like it's been rejected for now. ;-( Might just post everything and ignore the damage that doesn't apply... &{template:default} {{name=Attack}} {{Attack Roll=[[ 1d20 + @{selected|melee} ]] }} {{vs AC=[[ @{target|AC} ]] }} {{Normal Damage=[[ 1d6 ]] }} {{vs AC+8=[[ @{target|AC}+8 ]] }} {{Double Damage=[[ 2d6 ]] }}

Thanks Vince! That's exactly what I need. If it's not too much trouble, would you mind walking me through what each part of the syntax does? I may want to tinker later haha.

No problem; &{template:default} For this macro I used roll20's default  roll template . Most sheet's have there own roll templates which define how rolls will be handled (including a limited set of logic) as well as the look/layout of the output to chat. The "default" template is available to everyone regardless of the sheet.  {{name=Attack}} Roll templates use a simple {{property=value}} syntax.  this just says use "Attack" in the header of the output.   {{Attack Roll=[[ 1d20 + @{selected|melee} ]] }} Make a new line called "Attack Roll" and perform an inline roll.  [[ do stuff ]] The "selected|" portion states that the macro needs to pull the named attribute value from the selected token.  This would only work for linked tokens.(token is linked to a sheet)    {{vs AC=[[ @{target|AC} ]] }} new line called "vs AC" and pull a target's AC attribute.  You'll have to pick a target token.  Again, this assumes the token is linked to a sheet.  You could pull a value from a token's bar as well if you don't link monster's/npcs to sheets. ie [[ @{target|bar1} ]] {{Normal Damage=[[ 1d6 ]] }} new line called "Normal Damage" and make in inline roll of "1d6".  Of course this could be any amount... {{vs AC+8=[[ @{target|AC}+8 ]] }} new line called "vs AC+8" make an inline roll and pull the AC value of a target token, adding 8 to it.  This sets the double damage target number. {{Double Damage=[[ 2d6 ]] }} new line called "Double Damage" and make the double damage inline roll. This is a basic macro.  It could be made more flexible or complex as needed. ie You could add a query for damage instead of just using [[1d6 ]] example; [[ ?{Number of dice?|1}d?{Sides?|1} + ?{Modifier?|0} ]] Hope this helps.  Cheers

Thanks a bunch! I'll be able to implement this for some spells as well now. Also, how do I issue commands in chat? I tried typing #melee for example, but it just goes into chat as plaintext.

If you created a macro from the sidebar|collection tab and named it "melee", you should be able to type "#melee" in chat and hit enter/return. Entering "#" in chat will bring up a selectable list of your saved macros. If you are trying to call an attribute, all you need is the "@{ attribute name }"  If it's a sheet roll button try %{ button's name } often determined by hovering over a button on a sheet. The  help wiki has info on various commands and dice/roll functions used in chat. How to Roll Dice 3D Dice Dice Reference Macros Text Chat

thanks!
