Check multi-keys press

cvp

@yaley why do you set your activeKeys as False in changed?

DOGGY

@yaley Yes, sorry, as @cvp and my tries, using pygame module is not possible in Pythonista because Pythonista doesn’t have pygame Stash also cannot

yaley

@DOGGY It’s ok :)

yaley

@cvp oops that’s my wrong, but after changing it to True, it’s still not working, everything turns True, let me see the documentation carefully again.

After the key changed, the activeKey turns True, but then it will forever True, until next keyup

cvp

@yaley don't forget that presses is a kind of array with eventually multiple keys thus perhaps not only check [0]

DOGGY

@YaleY that would be a hard one…..

yaley

@cvp so what should i do now???? Can you show me the code with successful running?

cvp

@yaley said

Can you show me the code with successful running?

Ho no, you are further than me. I only try to think about it.
When you press the right arrow, your first key is still pressed?

yaley

@cvp yes, but the problem is when the second press joined CustomViewController_pressesChanged_withEvent_() didnt run about it

yaley

@cvp You’re method is correct, just i am stupid, i typed wrongly, i set the variable to True in the pressesEnded def

XD

cvp

@yaley right, just tested

yaley

Wait no, why??? Why my first test is correct and then the second test is not working?????

cvp

@yaley for me, changed not called
If you change something in a created class, restart Pythonista

yaley

@cvp here’s my code, I’ve tried to restart Pythonista

def CustomViewController_pressesBegan_withEvent_(_self, _cmd, _presses, event):
	global activeKeys
	presses = ObjCInstance(_presses).allObjects()
	keyCode = presses[0].key().keyCode()
	
	activeKeys[keyCode] = True
	
def CustomViewController_pressesEnded_withEvent_(_self, _cmd, _presses, event):
	global activeKeys
	presses = ObjCInstance(_presses).allObjects()
	keyCode = presses[0].key().keyCode()
	
	activeKeys[keyCode] = False
	
def CustomViewController_pressesChanged_withEvent_(_self, _cmd, _presses, event):
	global activeKeys
	presses = ObjCInstance(_presses).allObjects()
	keyCode = presses[0].keyCode()
	
	activeKeys[keyCode] = True

cvp

@yaley you should add some print in each method to check if called

cvp

@yaley said

keyCode = presses[0].keyCode()

Key() missing in changed

cvp

@yaley only began is called once with left arrow, second with right arrow

Thus, forget changed, and all is ok because two keys imply 2 calls to began

yaley

@cvp thanks it solved!!!

yaley

@cvp looks like i found the problem, if in the changed def, i set activeKeys[keyCode] = presses[0].key().keyCode() it doesn’t work, but if i set activeKeys[keyCode] = presses[0].keyCode() then it works :)

cvp

@yaley sorry, perhaps I (or my eyes) become too old, but I don't see the difference
