My character can only dash to the right

So im makin a platformer game , and i have the code setup to when i press space the character dashes , but for some reason when in air and i press space the character cant dash to the left, but if i press space for right he dashes perfectly fine, i noticed it doesnt work if i had left and up arrow down at same time but if i dont have the keys down it does it fine

That is called jamming https://en.wikipedia.org/wiki/Rollover_(key)#Ghosting.

Try another key instead of space like shift or control.

Wow thankyou, ur a lifesaver , i changed my jump button to ctrl and it works like a charm, now to return the favor, is there anything you need help with? Maybe something ur stuck on or cant figure it out, im also looking for teamates to collab with on projects
