While writing code, you may have heard or used Conditions. They are an essential to processing data and code.
As in basically every (or at least I hope every) coding language there are if and else statements, these statements check if a value returns true and if it does, it will run code inside of it
Here is an example in skript:
if player has permission "test.permission": #code else: #other code
In this example we are checking if the player has the permission "test.permission" using the Has Permission Syntax
In the If statement, it is checking the player's permissions, and if they have "test.permission" then it returns true. When it returns true, that means that the if statement will run the code inside of it.
The Else statement is basically a catch, if the if statement returns false (meaning the player does not have the "test.permission" permission) then the code inside the else statement will run.
In skript, you do not need to use if when doing a condition, you can just write the condition
player has played before: #code for if statement else: #code for else
This segment of code, is the same as using an if statement.
Although, In my own opinion, I believe using the If / Else is better practice and mentality for coding.
Another thing with conditions in skript is that to just check if a value is true, rather than using and if or having to indent, you can just check the condition.
Let me show you:
on join: player has not played before broadcast "this player (%player%) has not played before :O"
Now this segment of code checks if the player has NOT played before, by checking
player has not played before you are essentially doing a mini-if statement to check if that value is true, if the player has played before. As in the
player has not played before will return false then the broadcast statement will not run.
One More Thing...
In most coding languages (including skript) there is a thing called
else if this statement goes after an if statement and will run if the condition defined is true and then acts as its own else statement, this will only run if the connected if statement is false.then it tests if the condition is true, then runs. This is useful for checking multiple of the same thing, but if used incorrectly it could cause the if statements not to run, or run incorrectly.
Here's a short example:
on load: if 10 < size of offline players < 100: #checks that size of offline players is between 10 and 100 broadcast "%size of offline players%" else if 1< size of offline players < 10: # checks that the size is not 10-100 and that the size is 1-10 broadcast "Only a few amount of people have joined, its too much effort to display a number >:)" else: #size is neither 1-10 or 10-100 broadcast "WOW more than 100 people have joined, much pog"
Tip: If you have an if statement that you want to run and make 100000% sure that it does not continue to something else, then it is a good idea to use stop's
on join: if player has played before: send "Welcome back" stop else if player has not played before: send "WELCOME!!!!!!!" stop else: send "this will never happen,,,,,,, unless....." stop send "HI, im lonely no one sees me :("
Thank you, Hopefully this makes sense to you so you can use it in the future. I hope this helps you if you needed it.
