projectiles | gml

Add a new object objProjectile:

objPlayer Step

if (keyboard_check(vk_right)){ horiz = move_speed; };
if (keyboard_check(vk_left)){ horiz = -move_speed; };
if (keyboard_check(vk_nokey)){ horiz = horiz * frict; };
vert = vert + grav;

if (place_meeting(x, y+1, objBlock)) and (keyboard_check(vk_up)) { vert = jump_speed; }
    
if (place_meeting(x+horiz, y, objBlock)) { 
    while (!place_meeting(x+sign(horiz), y, objBlock)) { 
        x = x + sign(horiz); 
    }
    horiz = 0;
}
x = x + horiz;

if (place_meeting(x, y+vert, objBlock)) {
    while (!place_meeting(x, y+sign(vert), objBlock)) {
        y = y + sign(vert);
    }
    vert = 0;
}
y = y + vert;


//---------------------------- PROECTILES:

if mouse_check_button(mb_left){
    var inst = instance_create_layer(x,y,"Instances",objProjectile);
    with(inst){
        inst.direction = point_direction(x,y,mouse_x,mouse_y);
        inst.image_angle = direction;
        inst.speed = 10;
    }
}

Challenges

1. Implement the above code.

2. Find and replace the current key configuration to work with left hand for movement:

//Find and replace the keys to bind to ordinal characters:
ord("D") //instead of vk_right in player step event
ord("A") //instead of vk_left in player step event
ord("W") //instead of vk_up in player step event
//for example, instead of vk_left in player step event:
if (keyboard_check(ord("A"))){ horiz = -move_speed; };

3. CHALLENGE this code aims at the mouse position - can you make it so that the projectile fires in the direction the player is facing - left or right?

4. CHALLENGE what if the player is holding up or down - can the projectile go 4 ways? (up down left right)

5. Find a projectile sprite from the internet to use here - perhaps something animated NOT A BULLET AND NOTHING VIOLENT
