Function Documentation

EZ_change_text()

void EZ_change_text	(	EZ_text *	text_obj,
		char *	text,
		TTF_Font *	font,
		SDL_Color	color,
		SDL_Renderer *	renderer,
		int	auto_aspect )

Changes the text of an existing EZ_text object.

This function updates the text of an existing EZ_text object. It creates a new surface and texture from the provided text, font, and color, and updates the EZ_text object with the new texture and source rectangle. If auto_aspect is non-zero, the aspect ratio of the destination anchore will be automatically set based on the new surface dimensions.

Parameters

text_obj	The EZ_text object to be updated.
text	The new text to be rendered.
font	The TTF_Font to be used for rendering the new text.
color	The SDL_Color to be used for the new text.
renderer	The SDL_Renderer to be used for creating the new texture.
auto_aspect	If non-zero, the aspect ratio of the destination anchore will be automatically set based on the new surface dimensions.

Note

If the font is NULL, the function will terminate the program with an error.

If the surface or texture creation fails, the function will terminate the program with an error.

EZ_create_text()

EZ_text * EZ_create_text	(	char *	text,
		TTF_Font *	font,
		SDL_Color	color,
		SDL_Renderer *	renderer,
		anchore_point	dst_anchore,
		int	auto_aspect )

Creates an EZ_text object with the given parameters.

This function creates an EZ_text object, which includes rendering the text to a surface and creating a texture from that surface. The resulting texture is then used to create an EZ_DRAWABLE structure, which is stored in the EZ_text object.

Parameters

text	The text to be rendered.
font	The TTF_Font to be used for rendering the text.
color	The SDL_Color to be used for the text.
renderer	The SDL_Renderer to be used for creating the texture.
dst_anchore	The anchore_point for the destination.
auto_aspect	If non-zero, the aspect ratio of the destination anchore will be automatically set based on the surface dimensions.

Returns

A pointer to the created EZ_text object.

Note

If the font is NULL, the function will terminate the program with an error.

If the surface or texture creation fails, the function will terminate the program with an error.
