Some users would use a Timer object to do such a thing, but me I prefer to use cycles and seconds, this is because a Timer object does not start right away and it ends after an action has occurred. I use Timers for non-critical timing tasks. Cycles however, occur every physics frame and it takes 60 cycles to equal one second.
So, I suggest you create two global variables to keep track on cycles and seconds. These global variables must be initialized to zero at startup and they must also be reset to zero when they over-flow or when your slide input keys are not being pressed.
In the (physicsprocess) method you would increment (add + 1) to the cycle timer and you would check if it has overflowed (incremented up to 60 cycles). If it does, you would reset it to zero and you would increment the second counter by 1.
In your input key method you would use the second time counter to reduce the speed, if the second time counter is zero you would not lose any speed.
Once you let go of the sliding input keys, you will need to make sure to reset both the cycle and second time counters for next use!
You can call these global time counters as follows:
Note that you may want to use only the cycle counter since seconds may be too long. In this case you would only need the cycle counter to keep track of sliding time.
The following is code prototype which shows you what you need to do:
# Declare global cycle and second counters.
var CycleCount : int = 0; var SecondCount : int = 0
# Upon entering this method, we get input from user.
# Upon entering this method, increment the cycle counter by one.
CycleCount += 1
# Check for overflow?
# You can also check for
# lesser than 60 cycles,
# which reduces speed
# much quicker.
if CycleCount >= 60:
# On overflow, reset cycle counter.
CycleCount = 0
# Increment second counter.
# Here, you can increase the
# value to say 2 pixels which
# reduces speed by 2 pixels
# for every call to (GetInput)
SecondCount += 1
Note that this step will be different from your code, so just add appropriate code in its place.
# Upon entering this method, we check if user is pressing the sprint + crouch keys?
if Input.isactionpressed("sprint") == true and Input.isactionpressed("crouch") == true:
# If so, then we subtract seconds from current speed.
# Speed is assume to be global.
Speed = clamp(Speed - SecondCount, 0, Speed)
# Check if speed is zero?
if Speed <= 0:
# Here, you can perform an action when speed is zero,
# but is not necessary since actor will stop sliding.
# Never apply a zero speed to
# the actor movement vector.
# Else, actor will be position
# out of screen view.
# Else, reset cycle and second counters.
CycleCount = 0; SecondCount = 0
If you still cannot understand or perform the above, then I suggest you read the GDScript documentation to learn how to program. This forum is not a programming language tutorial site, for that you got Godot documentation and other web sites.
