How can i fix this weird error
I have this script so when i click space the character whould reach up and take a sword off his back, and when i click space i get this wierd error:
NullReferenceException: Object reference not set to an instance of an object walker.Update () (at Assets/my scripts/walker.js:22)
this is my script:
if(Input.GetButtonDown("Jump")) { var animationComp : Animation[] = gameObject.GetComponentsInChildren(Animation) as Animation[]; for (var animComp : Animation in animationComp) { animComp.Play("grab sword");
}
}
whats wrong?
my first question dose he at least take the sword out or dose it just give you the error right of the bat i would say if he is not taking out the sword at all it is most likely since this is java script that java script dose not know it as jump it knows it as space bar try this and tell me your result i hope this helps.
when i press space (with my script, it works) i get the error, not right off the bat
then i wold say tat when he takes out the sword he dose not no how to put his sword away try anding after the grab sword to say if(Input.GetButtonDown("Jump")) { Animation[] animationComp = gameObject.GetComponentsInChildren(Animation) as Animation[];
foreach (Animation animComp in animationComp) {
animComp.Play("put back sword");
}
} try this and see what happens
how would that help because if it didn't know how to put it back, then there would be no way to put it back but he would still take it out. $$anonymous$$y problem is when i click space i get an error and he does nothing.
Your codes says var it should be this:
if(Input.GetButtonDown("Jump"))
{
var animationComp : Animation[] = gameObject.GetComponentsInChildren(Animation);
for (animComp in animationComp)
{
animComp.Play("grab sword");
}
}

Edit: Oops, Don't Regularly use JavaScript, so I forgot to add var keyword... :)

Could you give it to me in JS because i Have a lot more to that script i just didn't post it because it did not have anything do do with this
