(SOLVED) About following and keeping key press

Hi there =)

I'm just newbie in construct 2 :p I just made few tutorials and i don't find any subject about my problem.

I'm making a conversion of maniac shooter and i'm looking for tips ^_^

How can i know if a key on keyboard is pressed during X seconds?

The key is also used to fire and when key is kept press it activate a shield.

When shield is active how should i do to make following or collide the 2 sprites during X seconds ?

Thanks a lot !

make a variable called "counting"

add 2 conditions

every x seconds

keyboard is down -> add 1 to "counting" variable

compare variable counting > 3 -> do something.

It would be easier to create an empty sprite, call it keyboardtimer and give it the timer behaviour.

on key pressed - keyboardtimer start timer "key" for x seconds

on key released - keyboardtimer stop timer "key"

keyboardtimer on timer "key"

• start shield
• keyboardtimer set timer "Shield" for x seconds

keyboardtimer on timer "Shield"

• stop shield

keyboardtimer.capx

Thanks for your replies guys :)

I think about my problem a little more, i'm going to try to explain but i'm not event fluent for now in construct :D

So i would like to make that : By pressing fast the fire button, this will activate or help to activate the shield.

OnKeyPressed

if(end+0.2<=now){ // 0.2 is in seconds (0.2s maximum between 2 keyPress)

Timer.begin; // reset of time begin

}

On KeyRelease

Timer.SetEnd(now);

Every 0.1 second

if(begin-end>=1.5){ // 1.5 in seconds

SpawnNewObject(Shield);

}

I think the algorithm is ok how can i translate thoses if statement in event?

Few explanations :

Timer wouls be an object with 2 members (begin and end)

begin represents the most recent time of key pressed (with a rule of buffering if the last one was less or equal to 0.2 seconds before the next one)

end represents the most recent time of key release

Finally i find how to make that!

Here my solution :

Create Sprite with Timer behaviour

Add 2 variable instance :

begin =0

end=0

Keyboard : on Spacebar released

=>Timer Set end to time

Keybord : on Spacebar is pressed

AND

Timer end <= time-0.2

=>Timer Set begin to time

System / Every 0.1 second

AND

Timer <= Self+1.5

=>Timer Set begin to 0

=>Timer Set end to 0

=>Player Spawn Shield

=> Timer Start Timer "Shield" for 4.0

Timer : on Timer "Shield"

=>Shield destroy

The last thing is to make follow the shield :)
