Help/Support expected '(' for function-style cast or type construction syntax error

[Tay-K 47 2 iPhone Xr 14.3]

hello, good evening. I keep getting this compile error when I try and compile my mod, 

Tweak.xm:25:62: error: expected '(' for function-style cast or type construction
ThirdPersonController_WalkSpeed(thirdPersonController, float value);

so like a normal person I took to google, I ended up finding that it was a c++ syntax error and I attempted their fixes.

the error remains. so I came here to get an experts help on what I messed up

here's the whole tweak xm code for what I've done.

#import "Macros.h"
#import <CoreFoundation/CoreFoundation.h>
#import <substrate.h>
#import <Foundation/Foundation.h>

//public void set_WalkSpeed(float value); // RVA: 0x18A5724 Offset: 0x18A5724 VA: 0x1018A5724
void(*set_WalkSpeed)(void *Update) = (void(*) (void *))getRealOffset(0x1018A607C);

    bool shouldactivateSuperSpeed = true;
    
void(*old_ThirdPersonController_Update)(void *thirdPersonController, float value);
void ThirdPersonController_Update(void *thirdPersonController, float value) {

int item = [[switches getValueFromSwitch:@"SuperSpeed:"]intValue];

if([switches isSwitchOn:@"SuperSpeed:"])

{

if(shouldactivateSuperSpeed)

{

ThirdPersonController_WalkSpeed(thirdPersonController, float value);

    shouldactivateSuperSpeed = false;
    
    }

}

else

{

    shouldactivateSuperSpeed = true;

    }
}

void setup() {

MSHookFunction((void *)getRealOffset(0x1018A607C), (void *)ThirdPersonController_Update, (void**)&ThirdPersonController_Update);
        
        [switches addTextfieldSwitch:@"SuperSpeed:"
            description:@"Here you can enter your own speed amount"
              inputBorderColor:UIColorFromHex(0xffffff)];
                
                
}

whoever sees this thank you and have a nice day.

You provided no type for

thirdPersonController

I suggest you learn C and C++ before starting off making cheats like this
