Conditional Code
Link to conditional-code
Onto more complex scripting! Conditional code is an important aspect of intermediate to advanced scripts.
Conditional code entails running a chunk of code if a boolean
condition evaluates to true
.
This allows you to execute code that can adapt to conditions in the world, the player, a block, or the entity that's dropping items.
If Statement
Link to if-statement
An if statement executes the piece of code if the boolean
inside of its bracket evaluates to true
.
ZenScript Copyval test = 0;
//test == 0 returns a boolean
if (test == 0) { //true
print("Test is zero!");
}
Else Statement
Link to else-statement
An else statement can be added to the end of an if statement to execute the block in case the if statement returns false, which means it did not execute.
ZenScript Copy
var test = 0;
if (test == 0) { //true
//will be executed when test is equal to 0
print("Test is zero!");
} else {
//will be executed when test is not equal to 0
print("Test is NOT zero!");
}
test = 1;
if (test == 0) { //false
//will be executed when test is equal to 0
print("Now, test is zero!");
} else {
//will be executed when test is not equal to 0
print("Now, test is NOT zero!");
}
Supported Operators
Link to supported-operators
Supported operators you can do calculations with are: +
, -
, +
, /
, %
.
Keep in mind you can also use the logic operators: !
, !=
, ==
, >
, >=
, <
, <=
, &&
, ||
, ^
Apart from these, as long as whatever is inside of the if bracket returns true, you can have anything in there!
Example:
ZenScript Copy
//In the context of an event:
if (!event.world.remote){
event.player.sendMessage(MCTextComponent.createStringTextComponent("Successfully completed action!"));
}
