zero is not zero
Hey, i have a problem with my code. i am trying to make an 2D Array of gameobjects. It works good so far. The only problem: In the Editor the Y value of the objects that are at 0 is not 0 but -9.536743e-07. In the scene window everything looks perfect and it does look like it is 0. But it does not show the 0 in the inspector.
Any ideas?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class DungeonManager : MonoBehaviour
{
public int dungeonGridSize = 7;
public float dungeonTileSizeX = 19.2f;
public float dungeonTileSizeY = 10.8f;
private float generationStartPosX, generationStartPosY;
private float currentGenPosX, currentGenPosY;
public GameObject[,] dungeon;
public GameObject emptyRoom;
// Start is called before the first frame update
void Start()
{
SetGenerationStartPos();
GenerateEmptyDungeon();
}
// Update is called once per frame
void Update()
{
}
void GenerateEmptyDungeon()
{
dungeon = new GameObject[dungeonGridSize, dungeonGridSize];
for(int i = 0; i < dungeonGridSize; i++)
{
for (int j = 0; j < dungeonGridSize; j++)
{
currentGenPosX = generationStartPosX + (i * dungeonTileSizeX);
currentGenPosY = generationStartPosY + (j * dungeonTileSizeY);
print(currentGenPosX);
print(currentGenPosY);
dungeon[i,j] = Instantiate(emptyRoom, new Vector2(currentGenPosX,currentGenPosY), Quaternion.identity);
}
}
}
void SetGenerationStartPos()
{
generationStartPosX = (((dungeonGridSize - 1) / 2)*dungeonTileSizeX)*(-1);
generationStartPosY = (((dungeonGridSize - 1) / 2)*dungeonTileSizeY)*(-1);
}
}
Hello! If your object is parented, then it is measured relative to the objects parent.
Since its a calculated float, 0.0000009 instead of 0.0000000 is probably a precision error but can be considered 0. As a side note, you never use X == 0.0f with floats because they rarely equal exactly 0.0000000.
