Player Collision Toggle

This dll allows you to modify collision of players and vehicles.
It can be used for challenge or racing servers, to prevent players interfering with each other.

Compiling

Create a blank win32 project in Visual Studio.
Place the files from PlayerCollisionToggle in the project.
Add the files to the project in Solution Explorer and click Build.

Installation

Install BlocklandLoader.
Place the compiled dll in Blockland/modules/.
Start Blockland.

Usage

Disabling collision for all vehicles

You can set collision between vehicles using the global setVehicleCollision(bool enabled) method.

Disabling collision for all players

You can set collision between players using the global setPlayerCollision(bool enabled) method.

Disabling collision for specific players

You can move a player to a second collision layer by changing it's typemask:

%player.setType((%player.getType() | $TypeMasks::PlayerObjectTypeHidden) & ~$TypeMasks::PlayerObjectTypeNormal);

And change it back like this:

%player.setType((%player.getType() | $TypeMasks::PlayerObjectTypeNormal) & ~$TypeMasks::PlayerObjectTypeHidden);

This allows other players to walk through it.

Raycasts and box searches

By default, searches only return players in the normal collision layer.
You can change this by using the $TypeMasks::PlayerObjectTypeHidden and $TypeMasks::PlayerObjectTypeAll masks for individual searches.
If you need to modify the default behavior, you can do something like this: $TypeMasks::PlayerObjectType = $TypeMasks::PlayerObjectTypeAll;

Modifying collision behavior (examples)

You will need to install MoveHandler for some of these to work. For unknown reasons MoveHandler crashes your server if you spawn a hole bot.

Prevent vehicles from colliding with any players:

$Physics::VehicleCollisionMask &= ~$TypeMasks::PlayerObjectTypeAll;

Allow vehicles to collide with all players:

$Physics::VehicleCollisionMask |= $TypeMasks::PlayerObjectTypeAll;

Allow players in the second layer to walk through players in the first layer:

function onPlayerProcessTick(%player, %move)
{
	if(%player.getType() & $TypeMasks::PlayerObjectTypeHidden)
	{
		$Physics::PlayerMoveMask &= ~$TypeMasks::PlayerObjectTypeNormal;
		$Physics::PlayerContactMaskServer &= ~$TypeMasks::PlayerObjectTypeNormal;
	}
	else
	{
		$Physics::PlayerMoveMask |= $TypeMasks::PlayerObjectTypeNormal;
		$Physics::PlayerContactMaskServer |= $TypeMasks::PlayerObjectTypeNormal;
	}
}

Players collide with other players in the same layer, and pass through players in the other:

function onPlayerProcessTick(%player, %move)
{
	if(%player.getType() & $TypeMasks::PlayerObjectTypeHidden)
	{
		$Physics::PlayerMoveMask &= ~$TypeMasks::PlayerObjectTypeNormal;
		$Physics::PlayerContactMaskServer &= ~$TypeMasks::PlayerObjectTypeNormal;

		$Physics::PlayerMoveMask |= $TypeMasks::PlayerObjectTypeHidden;
		$Physics::PlayerContactMaskServer |= $TypeMasks::PlayerObjectTypeHidden;
	}
	else
	{		
		$Physics::PlayerMoveMask &= ~$TypeMasks::PlayerObjectTypeHidden;
		$Physics::PlayerContactMaskServer &= ~$TypeMasks::PlayerObjectTypeHidden;

		$Physics::PlayerMoveMask |= $TypeMasks::PlayerObjectTypeNormal;
		$Physics::PlayerContactMaskServer |= $TypeMasks::PlayerObjectTypeNormal;
	}
}

Allow all players to collide with each other, but let players in the second layer walk through static shapes:

$Physics::PlayerMoveMask |= $TypeMasks::PlayerObjectTypeAll;
$Physics::PlayerContactMaskServer |= $TypeMasks::PlayerObjectTypeAll;

function onPlayerProcessTick(%player, %move)
{
	if(%player.getType() & $TypeMasks::PlayerObjectTypeHidden)
	{
		$Physics::PlayerMoveMask &= ~$TypeMasks::StaticShapeObjectType;
		$Physics::PlayerContactMaskServer &= ~$TypeMasks::StaticShapeObjectType;
	}
	else
	{
		$Physics::PlayerMoveMask |= $TypeMasks::StaticShapeObjectType;
		$Physics::PlayerContactMaskServer |= $TypeMasks::StaticShapeObjectType;
	}
}
