Armos->Next

Now that the kinks are worked out...(I think). This is a script request by BigJoe. It is an Armos FFC. It can spawn any enemy you want. I can be solid. If you leave the layer combo at 0 the FFC Combo swaps with the one under the FFC. Any other layer invisible combos will be used to avoid scrolling issues. For solidity and spawning sake the FFC will snap to the combo grid. Make sure the top right corner is in the combo you want it placed on.

This script also doubles as a Touch->Next (also BigJoe's idea) If you leave enemy(D0) argument at 0 the delay counter will determine how long Link must touch the combo before it changes. This only works with solid(D3) set to true or else the change will be instant.

The FFC can leave an item as with normal Armos. This will store a bit (D7) to a Screen->D slot (D6) so the item only drops once. As the namee suggests when the script is done the FFC switches to the combo to the immediate right of the FFC Combo.

Code:

//invisible combos used when setting to layers.
const int CMB_SOLID = 9; //an invisible solid combo.
const int CMB_INVIS = 8; //a non-solid invisible combo.

Please post if you find an issue.

To anyone who wants to use this script here is a tip: Make copies of the enemies you want to spawn and set their spawn type to instant. This will make the spawning look better.

A bug with the hitboxes causes the item saving portion of this script to sometimes not work. In order to fix it, you should change !LinkCollision(it) to it->isValid().

That should be easy enough, but for those who can't be bothered, here is the corrected script:

Code:

//invisible combos used when setting to layers.
const int CMB_SOLID = 9; //an invisible solid combo.
const int CMB_INVIS = 8; //a non-solid invisible combo.

ffc script ArmosNext

        void run(int enemy, int sfx, int delay, bool solid, int layer, int itemDrop, int d, int bit)
        {
                this->X = (this->X>>4)<<4; this->Y = (this->Y>>4)<<4; //align to combo grid
                int posX = this->X;
                item it;
                int wait = delay;

                if(solid){
                        if(!layer)
                                SetLayerComboD(layer, ComboAt(this->X, this->Y), this->Data);
                        else
                                SetLayerComboD(layer, ComboAt(this->X, this->Y), CMB_SOLID);
                }
               
                while(!LinkCollision(this)) Waitframe();

I'll modify the original post to include BigJoe's fix. I am still trying to think of the best way to do it. If anyone has any ideas check out my thread in Scripting Discussion.
