Sopinien said: I am indeed playing in a Premium Game (at least for the spoken of character). However i do not have GM Access. Could it be something about Permisions too ? something my GM has to enable? APILogic and Meta Scripts also throw big ? for me for now. If you could Provide links to these that would be awesome. Otherwhise ill just google it. There are particular scripts that would require GM rights (like Bump), and there are configurations that a script might offer the GM to apply which would give the players more access to functionalities of the script (like TokenMod opening up the "players can use ids" setting). However, I don't think these are your issue. First, you have to make sure that the scripts are installed in the game. Since you don't have GM rights, you have to ask a GM to install them. On the game page for a GM, there will be a "Settings" drop down where they can get to API Scripts, and from there they can copy/paste in script code or install them from the one-click. In your case, you're looking to have either/or of TokenMod and AlterBars installed. Once they are installed, the sandbox can still break and/or go stale, and can require rebooting. This is also a function of the GM, so if at some time you realize that you're getting no output for the script command you are sending through the chat, you will have to reach out to have the sandbox rebooted. I am pretty sure you're running into one of those two cases being true. Once you've installed the scripts and/or rebooted your sandbox (and your sandbox reboots every time you install a script), you should see responses from chat commands that should drive API function. (Also, you could ask your GM to check out the APIHeartbeat script, which gives a visual indication in your game that the sandbox is up and functional.) As for Meta-Scripts... those are scripts (written like other scripts) which interact with the message before normal scripts get the message, adding capability or function to the command line. They don't exist as an end to themselves, but as a way to give other scripts more ability. They use the fact that the message object generated from a single chat entry is handed off one API script to the next ( diagramed and discussed here ). Most "normal" scripts that are an end to themselves have to check whether they should take action on a message; meta-scripts do not. They figure if you are using their recognized syntax structures (like {& if ...} for APILogic, or @(selected...) for Fetch, etc.), then you intend for them to do what they do. I released a handful of meta-scripts and a controlling framework ( ZeroFrame ) as the Meta Toolbox . What you are looking to do would be an APILogic construction. I will probably not get the math of the inline roll right (to match your homebrew), but as an example: !{& if [[1d20+@{Berserker|wisdom_save_bonus}]].value >= 12}token-mod --set bar3_current|+1{& else}Barely... controlled... rage... {&simple}{& end} Note that this is built to be run from anywhere - not just from your character sheet - because I included a name for the character (here, Berserker). Replace that with your character's name to get it to work. If the condition in the IF token passes, then the token-mod command is included. If it fails, the ELSE case is included, which includes a SIMPLE token to turn it into a simple chat message (no longer an API message). That's a really basic example using a single simplified "what-if" from your homebrew. It sounds like your full homebrew would have more cases and more interactions of rolls and saves and levels. With that complexity, other meta-scripts might be helpful (something like Muler or Fetch). If you have any question about going that route, post back with more details about your setup. POST SCRIPT: I should probably mention that Kurt's ScriptCards is another script that could help you. ScriptCards isn't a meta-script (it is an end to itself), but it acts like a command line interface to let you build complex custom procedures for your macro (including ifs and cases). Meta-scripts still work with SC, and they are quite often used, but SC would be responsible for calling tokenmod and/or alterbars.
