This method draws an ASCII character at the specified position over time. The character is linearly interpolated from the starting position to the ending position over the specified amount of time.

Parameters

x	The X position of the character.
y	The Y position of the character.
character	The character to use when drawing the text.
text	The text to draw.
time	The amount of time, in seconds, to draw the character.

Canvas_drawText_anim()

void Canvas_drawText_anim	(	int	x,
		int	y,
		const char *	text,
		double	time )

Draws text at the specified position over time.

This method draws text at the specified position over time. The text is linearly interpolated from the starting position to the ending position over the specified amount of time.

Parameters

x	The X position of the text.
y	The Y position of the text.
text	The text to draw.
time	The amount of time, in seconds, to draw the text.

Canvas_drawText_anim_reverse()

void Canvas_drawText_anim_reverse	(	int	x,
		int	y,
		const char *	text,
		double	time )

Draws text at the specified position over time, then reverses the animation.

This method draws text at the specified position over time. The text is linearly interpolated from the starting position to the ending position over the specified amount of time. After the animation is complete, the text is then reversed back to the starting position.

This method will draw the text in reverse, starting from the last character and moving to the first character.

Parameters

x	The X position of the text.
y	The Y position of the text.
text	The text to draw.
time	The amount of time, in seconds, to draw the text.

Canvas_fillRect_anim()

void Canvas_fillRect_anim	(	int	x,
		int	y,
		int	width,
		int	height,
		char	c,
		double	time )

Fills a rectangle at the specified position over time.

This method fills a rectangle at the specified position over time. The rectangle is linearly interpolated from the starting position to the ending position over the specified amount of time, using the specified character.

The animation begins by filling the top row of the rectangle, then the second row, and so on until the entire rectangle is filled.

Parameters

x	The X position of the rectangle.
y	The Y position of the rectangle.
width	The width of the rectangle.
height	The height of the rectangle.
c	The character to use when filling the rectangle.
time	The amount of time, in seconds, to fill the rectangle.

Canvas_hLine_anim()

		int	y,
		int	width,
		char	c,
		double	time )

Draws a horizontal line at the specified position over time.

This method draws a horizontal line at the specified position over time. The line is linearly interpolated from the starting position to the ending position over the specified amount of time, using the specified character.

Parameters

x	The X position of the line.
y	The Y position of the line.
width	The width of the line.
c	The character to use when drawing the line.
time	The amount of time, in seconds, to draw the line.

Canvas_hLine_anim_reverse()

void Canvas_hLine_anim_reverse	(	int	x,
		int	y,
		int	width,
		char	c,
		double	time )

Draws a horizontal line at the specified position over time, then reverses the animation.

This method draws a horizontal line at the specified position over time. The line is linearly interpolated from the starting position to the ending position over the specified amount of time, using the specified character. After the animation is complete, the line is then reversed back to the starting position.

This method will draw the line in reverse, starting from the right side of the line and moving to the left side.

Parameters

x	The X position of the line.
y	The Y position of the line.
width	The width of the line.
c	The character to use when drawing the line.
time	The amount of time, in seconds, to draw the line.
