Access x value in list of Vector3
I've made a list of all possible x/y coordinates with my map area:
for(int x = 0; x <= worldWidth; x++)
{
for(int y = 0; y <= worldHeight; y++)
{
//makes a list of all possible positions for tiles
gridPositions.Add(new Vector3(x, y, 0f));
}
}
I've figured how to render a tile at every position, but next I need to apply a dozen more restrictions to create a landscape. To do this I need to access the x and y values of entries in my list, and I know in javascript and it would be something like gridPosition[i].x , but I'm unsure how to get it in Unity. Thanks!
I hadn't, but now that I've actually learned a bit more about C# I realize a lot of it is identical to Javascript, which will save me a lot of reading from here out.
From your example, gridPositions would appear to be of type Vector3, so you should be able to do as you suggested. ".x" after the Vector3 variable will return the x component as a float. You may want to have a look at the Vector3 scripting reference for this instance.
I think you answered your own question. You will need to declare gridPositions as an array and I usually set the size before hand.
Vector3[] gridPositions;
gridPositions = new Vector3[worldHeight];
for(int x = 0; x <= worldWidth; x++) ..... rest of code
Then to access x value:
tempFloat = gridPosition[I].x;
You've called your list gridPositions, so it's gridPositions[i].x, not gridPosition[i].x.
