okay yeah, still only nudges the

[glacial vault]

We should probably have made a thread long ago

what does the final code look like now

[glacial vault]

oh you did the parentheses wrong

the final closing parentheses should go where I marked, not at the end

you included the / gravity bit, which shouldn't be there

the point was to have (ALL THE STUFF) / gravity

like in the formula we had

[nocturne ravine]

ye alright, must've misread your messages I'll see if this fixes it

changing it to this: did seemingly nothing surprisingly

[glacial vault]

so what behavior are we seeing now?

it's going to the right height, and in the right direction, but not going far enough?

[nocturne ravine]

I'm trying to test an enemy, that's why I need the projectiles lol

here:

[glacial vault]

can you switch that to an MP4

[nocturne ravine]

yeah sure one sec

[glacial vault]

and it will embed in Discord

[glacial vault]

ok so we need to debug the code now

I would start with this:

At the end of the function log some stuff:

Debug.Log($"Time of flight: {timeOfFlight}. Distance to target: {horizontalDistance}");```

See if the numbers it's spitting out make sense

based on the video the time of flight should be something around 3 ish

[nocturne ravine]

alright lemme give this a go

[glacial vault]

although to be honest, that doesn't look like a gravity of 12 to me

[nocturne ravine]

I mean it is?

[glacial vault]

fair enough

oh one other thing

make sure your rigidbody on the projectile has drag set to 0

linear drag

if it has drag that's going to completely destroy this whole calculation lol

[nocturne ravine]

okay here's what the values are giving: you seen the video and I don't think that time of flight is correct

[glacial vault]

that time of flight is wrong yeah

that's why it's not going far enough

it thinks it has 10 seconds to reach the horizontal distance, so it goes too slow

in reality it only has about 3 seconds

so something is wrong with our time of flight calculation 😢

[nocturne ravine]

chatgpt cursed you lol

[glacial vault]

can you try - in the time of flight calculation - using -gravity every time you see gravity

that is certainly a possibility lmao

[nocturne ravine]

ye gimme a second

[glacial vault]

BTW another interesting thing to log here might be timeOfFlightMinus and timeOfFlightPlus

If the calculations are correct the smaller of the two should be very close to zero or even negative

Oh wait

I see something else wrong too

[nocturne ravine]

okay changing the code to this: made it go half the distance for some reason

[glacial vault]

Wait no I don't nvm

Did you miss the other gravity instances there?

There's the gravity * 2 in the middle

[nocturne ravine]

okay and also the time of flight is now 7 which would be double what it's supposed to be

[nocturne ravine]

making those negative broke it

and gave NaN

[glacial vault]

I see 🤔

[nocturne ravine]

so I tried different variations

[glacial vault]

Oh wait

I think I know the issue

Revert that change

One sec lemme type this out

so basically calculatedDesiredHeight is wrong there

it's correct for the yVel calculation

but for the time of flight calculation it should be initialHeight - target.position.y

[nocturne ravine]

giving that a go its loading

@glacial vault this worked! Thanks again for helping solve this hellscape of a problem!

[glacial vault]

can i see a video?

[nocturne ravine]

this worked too for some reason btw:

[glacial vault]

want to see it in action 😛

[nocturne ravine]

and yeah

[glacial vault]

i think this works too because essentially we're just getting the opposite end of the parabola, and then the logic to take the larger one "fixes" it. I Actually don't think it would work if you were standing at a different height than the cannon

in any case you should test when the player is above or below the thing

You may also want to have logic where like if ((playerHeight - enemyHeight) > desiredHeight) // don't shoot at all because we can't reach

[nocturne ravine]

okay here

[glacial vault]

awesome!

[nocturne ravine]

i'll get to testing those right now, but the enemy shooting regardless of if it can hit the player is apart of the design still.

[glacial vault]

gotcha. In that case you'll have to do something special because you're going to end up with like... infinity or NaN for the TimeOfFlight calculation

so you'll have to basically decide on a horizontal velocity somewhat arbitrarily.

I guess maybe you could make the horizontal velocity equal to the vertical velocity in that case. That will give you a 45 degree angle which will result in the farthest possible shot (but it still won't hit the player)

[nocturne ravine]

me being above the enemy and below the enemy always works btw

[glacial vault]

nice

[nocturne ravine]

this code seems to work perfect for my needs, I don't think I need to change it?

[glacial vault]

what about when you're more than desiredHeight higher than the enemy?

Or is that not possible?

[nocturne ravine]

i'll try

hm yeah you're right, going above the desired height it does the NaN stuff again

[glacial vault]

yup! You'll need a special case.

[nocturne ravine]

might just get the distance of the player and either increase desired height to the original desired height + the player y position, or just make the enemy not shoot and make it try to get closer

[glacial vault]

those are certainly options

at this point it's more of a game design question. Have fun!
