Remove tile from tilemap - mycats - 05-13-2020

Hi! I am trying to remove tile from tilemap (for ring collision) with this code:

Code:
if(ring_found)

{

    PlaySoundId(7);

    TLN_SetTilemapTile(foreground_tilemap,tileinfo.row,tileinfo.col,TLN_Tile(0));

    TLN_SetLayer(LAYER_FOREGROUND,NULL,foreground_tilemap);

    rings++;

}

But it gives Invalid Pallete reference when running SetLayer(). Any solution?

Are you using the same assets you posted some days ago?

It's not needed to reconfigure layer with TLN_SetLayer() once you modify the tilemap with TLN_SetTilemapTile(), they're already linked.

Removed SetLayer(), still not removing tile. But no more errors in log.

Are you passing the correct row and column? The following code works for me, when I press input 1, it removes the first ring:

Code:
    while (TLN_ProcessWindow()) {

        if (TLN_GetInput(INPUT_BUTTON1)) {

            Tile tile = {0};

            TLN_SetTilemapTile(foreground_tilemap, 54, 6, &tile);

        }

        TLN_DrawFrame(0);

    }

Thanks! You need to define empty tile before setting it and use

Code:
Tile tile={0};

TLN_SetTilemapTile(foreground_tilemap,tileinfo.row,tileinfo.col,&tile);

instead of

Code:
TLN_SetTilemapTile(foreground_tilemap,tileinfo.row,tileinfo.col,NULL);

Welcome!

I understand the confusion, it seems more intuitive to delete a tile passing just NULL instead of a valid pointer with index 0, right? I'll add this behavior in next update
