Info

splash_show_text(fname,delay) Shows a text splash screen. fname is the name of the text file. You can either display standard text files (.txt) or rich text files (.rtf). Rich text files can e.g. contain images. delay indicates the delay in milliseconds before returning to the game. use 0 to wait until the player presses the escape key or clicks with the mouse in the window. splash_show_image(fname,delay) Shows an image splash screen. fname is the name of the image file. Many image types are supported (for example .bmp, .jpg, .tif, and .wmf) but no animated images. delay is the delay in milli seconds before returning to the game. You can change the way the splash screens are displayed using the functions below: splash_set_main(main) Indicated whether the splash screen must be shown in the main game window (true, default) or in a separate window (false). splash_set_scale(scale) Sets the scale factor to be used when displaying a splash video or image. When using a value of 0 the scale factor is chosen such that the window is filled (default). splash_set_cursor(vis) Sets whether the cursor should be visible in the splash screen. Default it is visible. For movies the cursor cannot be switched off. splash_set_color(col) Sets the color of the area surrounding the image or video. splash_set_caption(cap) Sets the caption for the splash window. This only has effect when is a separate splash window is used. Default the empty string is used. splash_set_fullscreen(full) Indicates whether to use a full screen window or not. This only has effect when is a separate splash window is used. Default a normal window is used. splash_set_border(border) Indicates whether the window should have a border. This only has effect when is a separate normal splash window is used. Default a border is used. splash_set_size(w,h) Sets the size of the splash window. This only has effect when is a separate normal splash window is used. Default size is 640x480. splash_set_adapt(adapt) Indicated whether the size of the window must
e adapted to the scaled size of the video or image. This only has effect when is a separate splash window is used. Default adapt is true. splash_set_top(top) Indicates whether the window should stay on top of other windows. This only has effect when is a separate splash window is used. Default the value is true. splash_set_interrupt(interrupt) Indicates whether the game play should be interrupted while showing the splash window. This only has effect when is a separate splash window is used. Default the value is true. splash_set_stop_key(stop) Indicates whether to stop the display of the splash screen when the player pressed the Escape key. Default the value is true. splash_set_stop_mouse(stop) Indicates whether to stop the display of the splash screen when the player pressed the mouse inside the splash screen. Default the value is true. There is one particular type of splash info, which is the game information that the user can enter in Game Maker. You can display it using the following function. You can also load a separate info file. This is closely related to the displaying of the text splash screen but the display is governed by the settings provided when defining the game information and not by the settings above. It is also displayed in a different window, so it is possible to display both the game information and a splash screen at the same moment. These functions also work in the Lite Edition. show_info() Displays the game information window. load_info(fname) Loads the game information from the file named fname. This should be a rich text file (.rtf). This makes it possible to show different help files at different moments. Note that contrary to the spash screens, this rtf file cannot contain images. Pop-up messages and questions A number of other functions exist to pop up messages, questions, a menu with choices, or a dialog in which the player can enter a number, a string, or indicate a color or file name: show_message(str) Displays a dialog box with the string as a message. show_message_ext(str,but1,but2,but3) Displays a dialog box with the string as a message and up to three buttons. But1, but2 and but3 contain the
