One-way Block script

[C-Dawg]

The FFC script for a one-way block seems really simple, so I gave it a whirl. Problem is, the compiler doesn't like the Link->DownPressed() function, or it's relatives. Tells me there is no such function. According to Jman's ZScript documentation, there is... am I missing something in the syntax?

// =====================================
// No_South: While on the tile that this
// FFC occupies, Link will not be able to
// move south.
// =====================================


ffc script no_south {

	void run(){

		if ((Link->X >= this->X - 8) && (Link->X <= this->X +8) &&
		(Link->Y >= this->Y - 8) && (Link->Y <= this->Y +8) &&
		(Link->UpPressed() == true) ){

			Link->Y = Link->Y + 4;
		}
	
	} // end of void run
} // end of ffc script



// =====================================
// No_North: While on the tile that this
// FFC occupies, Link will not be able to
// move North.
// =====================================


ffc script no_north {

	void run(){

		if ((Link->X >= this->X - 8) && (Link->X <= this->X +8) &&
		(Link->Y >= this->Y - 8) && (Link->Y <= this->Y +8) &&
		(Link->DownPressed() == true) ){

			Link->Y = Link->Y - 4;
		}
	
	} // end of void run
} // end of ffc script


// =====================================
// No_East: While on the tile that this
// FFC occupies, Link will not be able to
// move East.
// =====================================


ffc script no_east {

	void run(){

		if ((Link->X >= this->X - 8) && (Link->X <= this->X +8) &&
		(Link->Y >= this->Y - 8) && (Link->Y <= this->Y +8) &&
		(Link->RightPressed() == true) ){

			Link->X = Link->X - 4;
		}
	
	} // end of void run
} // end of ffc script


// =====================================
// No_West: While on the tile that this
// FFC occupies, Link will not be able to
// move East.
// =====================================


ffc script no_west {

	void run(){

		if ((Link->X >= this->X - 8) && (Link->X <= this->X +8) &&
		(Link->Y >= this->Y - 8) && (Link->Y <= this->Y +8) &&
		(Link->LeftPressed() == true) ){

			Link->X = Link->X + 4;
		}
	
	} // end of void run
} // end of ffc script

EDIT: I suppose I could just have one function that gets passed an argument from the FFC to tell it which directions are blocked instead. I'd still have the same problem.

NOTE: If people are making 2-D games, some script like this will help you make platforms, as in Mario 2, that you can jump up through but not fall down through.

That documentation's out of date. It's no longer a function called DownPressed(), but a bool called InputDown.

Ah, well, there we go. Thanks.

What the... now, when I code:

if (Link->InputDown == true)

or

if (Link->InputDown == 1)

I get an "error: cannot cast bool to float" error message.

I believe the == operator is currently only defined for numbers. Just use if(Link->InputDown) instead.
