Quake 2 Double Jump

[ArchAngel]

Ok I'm trying to code a double jump function in Quake 2 similar to what we see in Unreal Tournament (not just the physics exploit), however what I've got doesn't seem to work at all.

In pmove.c:

in pml_t -
Add -

Code: Select all

qboolean	doublejump;	//EGL Double Jump support

In PM_CheckJump
Change

Code: Select all

if (pm->groundentity == NULL)
  return;

to

Code: Select all

if (pm->groundentity == NULL)
	{
		if(pml.doublejump == false)	//EGL Double Jump
		{
			pml.doublejump = true;
			if(pml.velocity[2] > 0)	//Still rising?
			{
				if(pml.velocity[2] < 270)
					pml.velocity[2] = 270;
			}
		}
		return;		// in air, so no effect
	}

While the double jumping bit works fine, the check to see if we're already double jumping does nothing at all. I'm wondering if the pml struct is recreated per frame and so being wiped.

Any thoughts?

(Incidentally EGL has nothing to do with EGLQuake... them's just my initials)

Fixed it

Code: Select all

if (pm->groundentity == NULL)
	{
		if(pm->s.pm_flags & PMF_DOUBLE_JUMP)	//EGL Double Jump
		{
			pm->s.pm_flags |= PMF_JUMP_HELD;
			pm->s.pm_flags  &= ~PMF_DOUBLE_JUMP;
			if(pml.velocity[2] > 0)	//Still rising?
			{
				if(pml.velocity[2] < 270)
					pml.velocity[2] = 270;
			}
		}
		return;		// in air, so no effect
	}

	pm->s.pm_flags |= PMF_JUMP_HELD;

	pm->groundentity = NULL;
	pml.velocity[2] += 270;
	if (pml.velocity[2] < 270)
		pml.velocity[2] = 270;
	pm->s.pm_flags |= PMF_DOUBLE_JUMP;
