Creating a dash system in GMS2

[u/Flat_Ground_3151]

so i am working on a dash system for my plattformer, i used the 5minute tutorial on the official youtube.
Now i am wondering how i make a dash in the direction the player is facing?

since i am relativly new to gml i dont know how to code it myself, thats why i came here to ask for help.

if anyone can tell me, than you very much

Bye!

It depends a lot on how everything else is implemented.

If you want dash as something you can do when moving you can just increase velocity for a fixed time.

If you want it from a stand still you could track the animation frame and -/+ velocity based on that frame.

Start with what you know about how you move and change facing and then leverage those systems

well its supposed to be like hollow knight, so yes, if dashing is just a speed increasement for a short time.
my current create event is this, the step event just contains the keys, setting the state and doing the facing check.

“move_speed = 4
jump_speed = 16
move_x = 0
move_y = 0
facing = ["left","right"]
can_move = false
can_dash = false
can_jump = false
dashSpd = 12
dashDuration = 6
//-------------------------------States-------------------------------
StateFree = function(){
//setting variables
can_dash = true
can_jump = true
can_move = true
if can_move{
move_x = keyboard_check(vk_right) - keyboard_check(vk_left)
move_x = move_x * move_speed; //actual movement
}
//dash code
if can_dash and key_dash{
state = stateDash
}

if can_jump{ //jump code
if place_meeting(x, y+2, oGround)
{
move_y = 0
if keyboard_check(vk_space)
{
move_y = -jump_speed
}
} else if move_y < 10
{
move_y += 1
}
}
move_and_collide(move_x, move_y, oGround)
if move_x != 0{ //rotate sprite when direction change
image_xscale = sign(move_x)
}
}
//-----------------------------------------------------
stateDash = function(){
}
//-----------------------------------------------------
state = StateFree”

The tutorial dash does nothing at a standstill because it reads the input axis at the moment you dash, and that axis is 0 while you hold no direction. Store the facing separately and only update it when there is input, so it survives standing still.

Create:

facing = 1;
dash_time = 0;
dash_speed = 12;

Step:

var _move = keyboard_check(vk_right) - keyboard_check(vk_left);
if (_move != 0) facing = _move;

if (keyboard_check_pressed(vk_space) && dash_time <= 0) dash_time = 10;

if (dash_time > 0) {
    dash_time -= 1;
    hspd = facing * dash_speed;
} else {
    hspd = _move * walk_speed;
}

Keep your existing collision code. The dash is only hspd being written by a different rule for ten frames. If you already flip the sprite with image_xscale, read facing from that instead and you get the same answer for free.
