Detailed Description

Crosshair helper functions.

Helper functions for dealing with crosshairs in games. If you don't want to deal with handling accurate crosshairs in a variety of view modes (1st-person, 3rd-person, XR) then simply use one of the supplied functions.

Function Documentation

Cross_Draw()

void Cross_Draw	(	string	materialPath,
		vector	sizeXY
	)

Draws a crosshair on the screen with the desired material and size.

Parameters

materialPath	is the material to use.
sizeXY	is the size in pixels it is meant to take up on screen.

Cross_DrawRGB()

void Cross_DrawRGB	(	string	materialPath,
		vector	sizeXY,
		vector	colorRGB
	)

Draw a given crosshair on the screen, with variable color.

Parameters

materialPath	is the material to use.
sizeXY	is the size in pixels it is meant to take up on screen.
colorRGB	is the normalized color values to tint the surface with.

Cross_DrawRGBA()

void Cross_DrawRGBA	(	string	materialPath,
		vector	sizeXY,
		vector	colorRGB,
		float	alphaValue
	)

Draw a given crosshair on the screen, with variable color and alpha.

Parameters

materialPath	is the material to use.
sizeXY	is the size in pixels it is meant to take up on screen.
colorRGB	is the normalized color values to tint the surface with.
alphaValue	is the alpha values to use on the whole surface.

Cross_DrawSub()

void Cross_DrawSub	(	string	materialPath,
		vector	sizeXY,
		vector	sourcePosXY,
		vector	sourceSizeXY
	)

Draw a given crosshair on the screen, of only a section from a material.

Parameters

materialPath	is the material to use.
sizeXY	is the size in pixels it is meant to take up on screen.
sourcePosXY	is a normalized starting position within the material from which we should start drawing from.
sourceSizeXY	is the normalized size within the material from which we should draw from.

Cross_DrawSubRGB()

void Cross_DrawSubRGB	(	string	materialPath,
		vector	sizeXY,
		vector	sourcePosXY,
		vector	sourceSizeXY,
		vector	colorRGB
	)

Draw a given crosshair on the screen, of only a section from a material, with variable color.

Parameters

materialPath	is the material to use.
sizeXY	is the size in pixels it is meant to take up on screen.
sourcePosXY	is a normalized starting position within the material from which we should start drawing from.
sourceSizeXY	is the normalized size within the material from which we should draw from.
colorRGB	is the normalized color values to tint the surface with.

Cross_DrawSubRGBA()

void Cross_DrawSubRGBA	(	string	materialPath,
		vector	sizeXY,
		vector	sourcePosXY,
		vector	sourceSizeXY,
		vector	colorRGB,
		float	alphaValue
	)

Draw a given crosshair on the screen, of only a section from a material, with variable color/alpha.

Parameters

materialPath	is the material to use.
sizeXY	is the size in pixels it is meant to take up on screen.
sourcePosXY	is a normalized starting position within the material from which we should start drawing from.
sourceSizeXY	is the normalized size within the material from which we should draw from.
colorRGB	is the normalized color values to tint the surface with.
alphaValue	is the alpha values to use on the whole surface.
