Overview

RiveSMIInput is the base class for all State Machine input types. It provides common functionality for identifying and working with inputs in Rive state machines. All input types inherit from this class:

​
Type Checking Methods

​
name

- (NSString*)name;
Returns the name of the input as defined in the Rive editor. Returns: The input’s name as an NSString

​
isBoolean

- (bool)isBoolean;
Checks if this input is a boolean type. Returns: true if the input is a RiveSMIBool, false otherwise

​
isTrigger

- (bool)isTrigger;
Checks if this input is a trigger type. Returns: true if the input is a RiveSMITrigger, false otherwise

​
isNumber

- (bool)isNumber;
Checks if this input is a number type. Returns: true if the input is a RiveSMINumber, false otherwise

​
Usage Example

// Get an input from a state machine
RiveSMIInput* input = [stateMachine inputFromName:@"myInput"];

// Check the input type
if ([input isBoolean]) {
    RiveSMIBool* boolInput = (RiveSMIBool*)input;
    [boolInput setValue:true];
} else if ([input isNumber]) {
    RiveSMINumber* numberInput = (RiveSMINumber*)input;
    [numberInput setValue:42.0];
} else if ([input isTrigger]) {
    RiveSMITrigger* triggerInput = (RiveSMITrigger*)input;
    [triggerInput fire];
}

NSLog(@"Input name: %@", [input name]);
