So it doesn't compile in newer versions of SM. I decided to try and update the syntax to get it to compile. For some reason enum structs (when to use then and when not and how to handle them) are what always throw me for a loop.

So my first attempt (code here - https://pastebin.com/xijWumi8 )was to update everything to new syntax as normal and the only error I'm left with is to update the enum to enum struct.

snake.sp(91) : warning 213: tag mismatch (expected "WormMode", got "int")
snake.sp(92) : warning 213: tag mismatch (expected "WormMode", got "int")
snake.sp(293) : warning 213: tag mismatch (expected "WormMode", got "int")
snake.sp(298) : error 153: Array-based enum structs have been removed. See https://wiki.alliedmods.net/SourcePawn_Transitional_Syntax#Enum_Structs
snake.sp(299) : warning 213: tag mismatch (expected "int", got "WormMode")
snake.sp(300) : warning 213: tag mismatch (expected "int", got "WormMode")
snake.sp(301) : warning 213: tag mismatch (expected "WormMode", got "int")
snake.sp(316) : warning 213: tag mismatch (expected "WormMode", got "int")
snake.sp(380) : warning 213: tag mismatch (expected "WormMode", got "int")
snake.sp(381) : warning 213: tag mismatch (expected "WormMode", got "int")

The warnings are all related to the same.

However I don't understand the difference here. Both of these enums appear to have set values and don't mix data types.

enum WormDirection
{
	Direction_Right = 0,
	Direction_Down,
	Direction_Left,
	Direction_Up
}

enum WormMode
{
	Mode_Snake1, // walls are solid
	Mode_Snake2 // walls are walkable
}

But I'm getting an error telling me to turn WormMode into an enum struct, but not for WormDirection.

Changing it to an enum struct introduces a lot more errors and complications that I can't seem to fix.

Now I have this code - https://pastebin.com/kALEd6se

And I have a lot more errors I don't know how to fix:
