Float positive and negative calculation isn't working - Meller - 05.10.2017

So basically, I'm trying to create a random generation of "tiles", but I can't calculate out the X and Y position from 0.0, 0.0 by using negative numbers but I can succeed with doing it with positive numbers.

As seen here; tile 4 is supposed to be on the corner of tile 1, west-south, not north-east.

Here's how their deployment is;

PHP код:



    public OnGameModeInit() {

        CreateTile(TILE_TYPE_GRASS, 0, 0);

        CreateTile(TILE_TYPE_GRASS, 1, 0);

        CreateTile(TILE_TYPE_GRASS, 0, 1);

        CreateTile(TILE_TYPE_GRASS, -1, -1);

        return 1;

    }

And the function is as following;

PHP код:



stock CreateTile(type, x, y) {

    new id = CreateObject(TILE_MODEL_ID, (x >= 0)?(x*125):(x*(-125)), (y >= 0)?(y*125):(y*(-125)), 30.0, 0, 0, 0);

    new string[144];

    format(string, sizeof string, "Tile: %i\nPosition: %i - %i", id, (x >= 0)?(x*125):(x*(-125)), (y >= 0)?(y*125):(y*(-125)));

    Create3DTextLabel(string, 0x1CC4FCFF, (x >= 0)?(x*125):(x*(-125)), (y >= 0)?(y*125):(y*(-125)), 30.0, 1000.0, 0, 0);

    switch(type) {

        case TILE_TYPE_GRASS: {

            SetObjectMaterial(id, 0, 9495, "vict_sfw", "Grass", 0);

            for(new Float:gYY = -62.5; gYY < 62.5; gYY += (float(random(50)+1)*0.1)+1)

                for(new Float:gX = -62.5, Float:gY = float(random(50)+1)*0.1; gX < 62.5; gX += (float(random(50)+1)*0.1)+1, gY = float(random(50)+1)*0.1)

                    CreateDynamicObject(TILE_OBJECT_GRASS, ((x >= 0)?(x*125):(x*(-125)))+gX, (((y >= 0)?(y*125):(y*(-125)))+gY)-gYY, 30, 0, 0, 0);

        }

    }


    staticTiles[id][staticTile_ID] =     id;

    staticTiles[id][staticTile_Type] =     type;

}

Any ideas of what I'm doing wrong?

-1Ч(-1)=+1
-1Ч1=-1

So your above calculations are always positive. You don't need to check if value of x and y is negative or positive.
Just keep them as they are with Ч125.
