Is this idea even possible?

[STGraves]

I was thinking on creating a way to disable collision detection when a switch is activated and not only deactivate it but also changing the three-dimensional position of the character, in other words allowing it to pass behind the PF, but I honestly couldn't think of a functional way to do so, any ideas, or better yet, is it even possible?

Have you looked at this yet:

[STGraves]

Yes I have but I couldn't get it to work, no I didn't just paste it the exact same way as it's written.

Does that program compile for you the way it is without making any changes?

[+Random Terrain]

I updated that program so it might be less complicated.

This flips the bit:

---

   _Bit2_Flip_CTRLPF{2} = !_Bit2_Flip_CTRLPF{2}

---

This puts what you need in CTRLPF:

---

   temp5 = 1 : temp5{2} = _Bit2_Flip_CTRLPF{2} : CTRLPF = temp5

---

Remember that when you use the individual bits of a variable to do simple on/off jobs, you can no longer use the whole variable for other jobs. For example, if you use one of the bits of the variable a, you can't use something like a = 48 or a = a + 1 in your program somewhere else. If you do, the bit you are trying to use in the variable a will end up getting overwritten.

Sorry for answering this late yes it does compile perfectly and runs, but the function doesn't work, let me try the new version, thanks.

I have one question can the variable be used in a different bit than 2?

[STGraves]

I see it can be done, now I wonder if it's possible to do it with switches instead of the fire button, because for some reason it crashes my game xD

[STGraves]

I got it to compile without crashing, I'm not sure if it's because the collision detection but my character can't go underneath the PF, do you think it has to do with that?

Say you have something like this:

 

---

   dim _Bit2_Flip_CTRLPF = y

---

   _Bit2_Flip_CTRLPF{2} = !_Bit2_Flip_CTRLPF{2}

---

   temp5 = 1 : temp5{2} = _Bit2_Flip_CTRLPF{2} : CTRLPF = temp5

---

 

And you want to use bit 7 instead of bit 2. Just do this:

---

   dim _Bit7_Flip_CTRLPF = y

---

   _Bit7_Flip_CTRLPF{7} = !_Bit7_Flip_CTRLPF{7}

---

   temp5 = 1 : temp5{2} = _Bit7_Flip_CTRLPF{7} : CTRLPF = temp5

---

 

Do not change the "temp5{2}" part of the code. If you changed it, that would be why you are having a problem.

[STGraves]

I think that's exactly the problem! I don't have my laptop here with me but I think I did changed the temporary bit to 5

It sounds like you're limiting yourself to a modified collision detection example. If you're writing your own engine then you can simply use a flag to determine whether you run collision event code.

 

if dontprocesscollision = 1 then goto nocollsions

[STGraves]

That's an awesome idea but I have no variables left free, and I can't clean them, but I have a idea which involves restructuring the game.

I'd see what you can do using individual bits instead of whole variables.

 

dim attributes = g

 

def isnekkid=attributes{0}

def victhere=attributes{1}

def victdead=attributes{2}

def gotmarla=attributes{3}

def doorhere=attributes{4}

def popohere=attributes{5}

def ghostgone=attributes{6}

def bulletsnow=attributes{7}

 

if isnekkid then goto flashing

Wow I still have a lot to learn I didn't know about using def

I had all kinds of mysterious problems when using def, so I stopped using it.
