-This function is what handles the context of the text. The `if (gSpecialVar_TextColor; != 0xFF)` if I’m honest I’m not sure what it does as of writing this. The else if check looks for the selected object event. This is 0 when interacting with signs or any other text that hasn’t been triggered by the player interacting with an object event. What we need to be paying attention to is the `gSpecialVar_TextColor = graphicsInfo->textColor;`. This is how the function gets the object event text colour.
+This function is what handles the context of the text. The `if (gSpecialVar_TextColor; != 0xFF)`… if I’m honest, I’m not sure what it does as of writing this. I think it looks for values that aren’t FF, if the value is FF, that particular snippet won’t do anything. The else if check looks for the selected object event.

 We need to define them to constants because `PrevTextColor` and `TextColor` can be used in scripts. So we need to go to `include/constants/vars` and find `#define VAR_UNUSED_0x08014` with `#define VAR_TEXT_COLOR` and add a new constant.
 The changes should look something like this:

+And with that, you should have successfully reimplemented `textcolor` and gave object events their own text colour.
