Hey everyone, so it's been a while since I delved into Zelda Classic, and I decided to load one of my old scripts Purplemandown made for me. It's a roll script and it worked REALLY well back when I used it, I did have one issue with it where you can slash in the middle of it. Any ideas how to fix this? Also, I made a new topic because I didn't want to gravedig. Hopefully this is okay. :)

global script slot_2{
    void run(){
        lweapon overlay;
        int rolltimer;
        int rollwait;
        int rollSpeed = 300;
        int rollDur = 25; //in frames
        int cooldown = 5;
        int firstSFX = 61;
        int rollSprite = 88; //The first of the 4 rolling sprites (in weapon/misc.)  In order, up, down, left, right.
		int puffSprite = 92; //The sprite to trail behind link as he rolls
        while(true){
            if((Link->PressR == false) && (rolltimer == 0) && (Falling == false)){
                overlay->DeadState = 0;
                Link->CollDetection = true;
                Link->Invisible = false;

    }
}

Thank you!

Bump

Anyone know of a way to have the roll script check for moving blocks? when you push a block, you can roll through it as it is moving.

"Screen->MovingBlockX" gives you the X position of the moving block, "Screen->MovingBlockY" gives you the Y position. Using that, you can add scripted collision for a 16x16 square where those coordinates represent the upper-left corner, preventing Link from moving through it.
As for how to do scripted collision, that's a whole 'nother question, and one I don't have time to answer right now.

Probably just disable rolling if there is a moving block with:

 

&& !Screen->MovingBlockX && !Screen->MovingBlockY

 

Otherwise, halt the script if Link's position is at the coordinates -/+ based on his dir.
