Syntax#

vngen_log_button_create(id, text, sprite, spr_hover, spr_select, x, y, z, font, color, [ease]);

`spr_hover`	sprite/macro	The sprite to display as a background when hovered (or keyword 'none' for default)
`spr_active`	sprite/macro	The sprite to display as a background when selected (or keyword 'none' for default)
`x`	real	The horizontal position to display the button, relative to the GUI layer
`y`	real	The vertical position to display the button, relative to the GUI layer
`z`	real	The drawing depth and list order of the button, relative to other log buttons only
`font`	font	The font to draw text in, where `fnt_default` is default

Description#

Creates a new button which will be displayed while the backlog is open. The chosen button ID will be recorded as the selected choice until cleared with vngen_get_log_button or vngen_log_button_clear. Buttons can selected by mouse/touch, or by other input devices with vngen_log_button_nav and vngen_log_button_select.

Unlike other entities, button z-index determines not just drawing depth, but also navigation order. Buttons with lower z-index will be considered lower in the list of buttons. If z-index is equal between two or more buttons, navigation order will automatically be set by reverse creation order, but this may or may not be visually correct. Therefore, it is recommended to always set z-index explicitly. The actual values used are inconsequential so long as they are ordered from highest to lowest.

Note that although this script resembles an action, it is not and should not be executed within VNgen events. Instead, log buttons should ideally be created in the Create Event of a dedicated backlog object.

See Macros & Keywords for a list of available ease modes.

Example#

vngen_log_button_create("up", "", spr_up, spr_uhover, spr_uactive, display_get_gui_width(), display_get_gui_height()*0.5, -1, fnt_default, c_white);
vngen_log_button_create("dn", "", spr_dn, spr_dhover, spr_dactive, display_get_gui_width(), display_get_gui_height()*0.5, -2, fnt_default, c_white);
