Hi all,
Chasing some logic ideas here. I’m pretty new at this.
I have a character running, jumping, etc. I want to implement a “dash” function to the character.
Pressing R makes character run, tapping and holding R again makes character dash.
I have a state setup happening where I have all my code in the R key as such:
if btn_right.check() == 2: #2 = pressed in the input_states.gd script
move(player_speed, acceleration, delta)
ORIENTATION_NEXT = "right"
anim = "run"
anim_speed = 2
anim_blend = 0.3
How would I go about putting a check in there for dashing or not?
I’ve considered these variables:
#dash variables
var dash = false #are they dashing?
var dash_time = 4 #how long they can dash for
var dash_speed = 2 #multiplier - how much faster than the normal run is the dash
I’m just at a loss of how to say and where to put something like:
check if R is pressed a second time
if so, then dash like a madpixelsprite
if key released, set dash to FALSE
I know I’ve almost answered it, I just can’t get it right unfortunately. Any help would be manna from heaven.
You’re heading in the right direction. The following should help assuming you’re using input_states.gd from ndee85 since you had btn_right.check(). The code has not been tested but I used a similar piece on a Unity project. The logic is the same so it should work.
var dashing = false # whether player is dash or not
var max_dash_delay = 0.5 # time between keypress (.5 secs)
var max_dash_time = 2.0 # how long player can run for (2 secs)
var dash_timer = 0 # timer to reset dash state
var dash_press_count = 0 # keep track of double tap count
var move_speed = 5 # the normal move speed
var dash_speed = 10 # the dash speed
var speed = 0 # used to store whichever speed the player is moving at
var velocity # the velocity which governs the player's movement
# using ndee85 state values [ 0 - released, 1 - just pressed, 2 - pressed, 3 - just released ] below for readability
var INPUT_RELEASED = 0
var INPUT_JUST_PRESSED = 1
var INPUT_PRESSED = 2
var INPUT_JUST_RELEASED = 3
_ready() :
speed = move_speed # default to the move speed
velocity = Vector2() # default velocity
_process(delta) :
# only attempt to dash if the player's not dashing
if (dash_action.check() == INPUT_JUST_PRESSED and not dashing) :
dash_press_count += 1
# start the dash timer when player just presses the dash action
if (dash_press_count > 0 and not dashing) :
dash_timer += delta
# the player took too long to perform the second tap so reset values
if (dash_timer > max_dash_delay) :
dash_timer = 0
dash_press_count = 0
# the player managed to dash successfully
if (dash_press_count >= 2 and not dashing) :
dashing = true
dash_timer = 0
dash_press_count = 0
# player now uses the dash speed until timer elapses
speed = dash_speed
# the player will continue to dash until the timer elapses
if (dashing) :
dash_timer += delta
if (dash_timer >= max_dash_time) :
dashing = false
dash_timer = 0
# timer elapsed, reset to the normal speed
speed = move_speed
# move using whichever speed is chosen
velocity += Vector2( speed * delta, velocity.y )
# assuming you're using kinematicbody2d otherwise use set_pos(velocity)
move (velocity)
