RuleTile implementation does not honor Default GameObject set in editor

[CodeMonkeyJC]

In the GetTileData method of the RuleTile script the gameObject is initially set to the default object (line: 206) in the RuleMatches if statement the "defaults" for the gameObject and collider type are always overwritten even if null. Lines 233/234.

Here is a solution i used:
if (RuleMatches(rule, position, tilemap, ref transform))
{
switch (rule.m_Output)
{
case TilingRuleOutput.OutputSprite.Single:
case TilingRuleOutput.OutputSprite.Animation:
tileData.sprite = rule.m_Sprites[0];
break;
case TilingRuleOutput.OutputSprite.Random:
var index = Mathf.Clamp(
Mathf.FloorToInt(GetPerlinValue(position, rule.m_PerlinScale, 100000f) *
rule.m_Sprites.Length), 0, rule.m_Sprites.Length - 1);
tileData.sprite = rule.m_Sprites[index];
if (rule.m_RandomTransform != TilingRuleOutput.Transform.Fixed)
transform = ApplyRandomTransform(rule.m_RandomTransform, transform, rule.m_PerlinScale,
position);
break;
}
tileData.transform = transform;
tileData.gameObject ??= rule.m_GameObject;
if (rule.m_ColliderType != m_DefaultColliderType)
tileData.colliderType = rule.m_ColliderType;
break;
}

Thanks! We will check this out and update the RuleTile.

Hi, the current behaviour of the RuleTile is valid and correct.

• If there is a Rule that matches, it will use the output from the Rule. A user may specifically want a null GameObject or collider type as set up for that Rule, which your changes would override.
• If there are no Rules that matches, then it would use the defaults as given.

To reduce any errors from having unwanted null GameObjects in a Rule when there are defaults set, in the RuleTileEditor, we will create Rules with the defaults set. This currently is not happening right now, but will be fixed in a future version of the package.

Hope this clarifies the issue!
