Warps

You can easily create warps in the Dink engine by setting a warp destination point, but performing the same task in DinkC is a bit tricky.

Here's an example script that performs the same task as a warp sprite. If you need to warp to a different screen in the middle of a cutscene, just copy the necessary lines out of the touch procedure.

// warp-eg.c by Ted Shutes
void main(void)
{
    // temporarily disable the touch() procedure
    sp_touch_damage(&current_sprite, 0);

    // set brain and pframe in case they weren't set by create_sprite():
    sp_brain(&current_sprite, 6);
    sp_pframe(&current_sprite, 1);

    // override create_sprite's pseq; start the warp sprite's animation:
    sp_seq(&current_sprite, 170);

    // set the animation rate to about 30 frames a second:
    sp_timing(&current_sprite, 33);

    // activate the touch() procedure after a second:
    wait(1000);
    sp_touch_damage(&current_sprite, -1);
}

void touch(void)
{
    // prevent more instances of touch() from starting:
    sp_touch_damage(&current_sprite, 0);

    // freeze Dink until the new screen is loaded:
    freeze(1);

    // keep script active after current screen and sprites are gone
    script_attach(1000);

    // optional pause for effect
    wait(500);

    // another optional effect - if not using, use sp_nodraw(1,1) instead
    fade_down();

    // screen to warp to, 1 to 768
    &player_map = 768;

    // Dink's X,Y coordinates on the new screen
    sp_x(1, 320);
    sp_y(1, 200);

    // face Dink in an appropriate direction, usually toward the player
    sp_dir(1, 2);

    // load screen specified by &player_map
    load_screen();

    // start music if desired
    playmidi("5.mid");

    // draw the screen's tiles and sprites
    draw_screen();

    // if sp_noclip() is in use in this dmod, redraw the status area
    draw_status();

    // undo fade_down(), or do a sp_nodraw(1,0) to undo a sp_nodraw(1,1)
    fade_up();

    // kill script manually, since we did a script_attach(1000) earlier
    kill_this_task();

    // note that no unfreeze(1) is required.
}
