- Clears a set of overlays in ranges [start,stop]. If unspecified, wipes all non-hardcoded layers. Safety determines whether to affect core layers or not (i.e. weapon). Returns the number of layers cleared.
Added no override boolean to A_Overlay and a boolean return type.
- If true, and a layer already has an active layer, the function returns false. Otherwise, sets the layer and returns true.
SPF_NOTIMEFREEZE processes particles with this flag regardless of time freeze. The endsize parameter changes the scale of the particle to that size throughout its lifetime linearly.
- Source is the actor to blame for the cause of damage (monster infighting for example). For missiles, modders should consider setting to AAPTR_TARGET.
- Inflictor is the actor doing the damage itself. Note that by changing this, it will take into account the flags on the pointed actor.
- Places the weapon offset by the defined x and y. Both are floats. This stacks with weapon bobbing.
- WOF_KEEPX: Don't change the X offset.
- WOF_KEEPY: Don't change the Y offset.
- WOF_ADD: Add onto instead of replacing the coordinates.
- float GetZAt(x, y, angle, flags, pick_pointer);
- Gets the floor z at x distance ahead and y distance to the side in relative form from the calling actor pointer. Flags are as follows (GZF_ prefix):
- CEILING: Returns the ceiling z instead of floor.
- ABSOLUTEPOS: x and y are absolute positions.
- ABSOLUTEANG: angle parameter does not add the pointer's angle to the angle parameter.
This fixes some jerkiness with vertical scrollers due to a bad sine period and makes the overall appearance of the effect what it was originally supposed to be. The old warp2 shader was not created by replicating the formula but by trial and error until it looked close enough.
A version of the old warp2 shader with a fixed sine period is still available as a custom hardware shader.
- FLATSPRITE: An actor becomes flat as if they were a decal on the floor.
- PITCHFLATSPRITE: A flat sprite tilts up and down based on pitch.
- WALLSPRITE: Similar to a Y billboarded sprite. The degree of the flattening is determined by the FlatAngle property.
- ROLLSPRITE: The sprite of the actor is affected by the Roll property.
Since decals may have thinkers attached this will crash when such a savegame gets loaded, because the thinker lists get reset in P_SerializeThinkers, deleting any thinker that already was processed.
I also added an error message that immediately aborts the save process if such an out-of-sequence thinker is attempted to be written out.
This obviously breaks savegame compatibility again...
The scripting branch changed camera semantics to default to an actor's center - which for monsters and decorations makes sense - but not for simple mapspots that get used as camera. For those the CameraHeight must be explicitly set to 0.
Unfortunately the math behind the old clip planes is utterly impenetrable and so poorly documented that I have no idea how to set that up, so it is deactivated for now. It wasn't working anyway.
* disable the dynamic light code if no buffers are available
* added a duplicate of the getTexel function which cannot be patched without creating syntax problems.
* fixe int<->float conversion warning, which on some compilers may be an error.
ZDoom defaulted to Boom's (buggy) angle adjustment.
Changed it so that
* Mode 0 is like Hexen, performing no adjustment at all. This still should match all known maps using this special.
* Mode 1 remains unchanged.
* Mode 2 replicates Boom's broken angle adjustment and is used in the xlat file.
* Mode 3 implements the correct angle adjustment that Boom originally intended.
(Note: Should some map require something different it should be handled with compatibility.txt instead of reverting this back to the broken way it was before.)
- This reverts commit 06216d733e.
- I don't know what I was thinking. Since stateowner is always available
to the wrapper function, and this code is only generated for the wrapper
function, it's a nonissue. The state is already located before calling
any function that uses it.
- This reverts commit 39df62b20e.
- Anything that needs to lookup a state also needs stateowner. See
FxMultiNameState::Emit(). I will need to be more selective when
de-actionifying functions.
- An actor function really only needs to be an action function if:
1. It can be called with no parameters specified, either because it takes
none or because all its parameters are optional. This lets SetState()
call it directly without creating a wrapper function for it.
2. It wants access to the callingstate or stateowner parameters. Most
functions don't care about them, so passing them is superfluous.
- Includes 2 flags, affixed by CBF_: AbsolutePos, and AbsoluteAngle.
- AbsolutePos: Absolute position of where to check.
- AbsoluteAngle: Angle parameter is used as is, not added onto the actor's current angle.
* Added falloff parameter to A_QuakeEx.
- Treated just like A_Explode's 'fullradiusdamage' parameter, where the quake will fall off from this distance on out to the edge. Default is 0, which means no falloff.
- Credits to MaxED and Michaelis for helping.
* - Added HighPoint parameter to QuakeEx.
- Allows fine tuning of where the quake's maximum or minimum occurs, in tics. This must be a range between [1, duration).
- For up or down scaling quakes, this sets the quake to reach maximum sooner or start minimizing later.
- For both, this indicates when the strongest will occur. Default is 0, or in the middle.
The original commits were nearly impossible to find in the convoluted commit tree, so I think it's preferable to have one clean commit instead.
- Converted P_MovePlayer and all associated variables to floating point because this wasn't working well with a mixture between float and fixed.
Like the angle commit this has just been patched up to compile, the bulk of work is yet to be done.
- This is an effort to emphasize that these are just type casts. Now they
look like function-style casts with no action function styling.
They do no magic joojoo at all. The only reason they exist is because
the DECORATE parser can only parse return statements that call a
function, so these satisfy that requirement. i.e. *return int(666);* is
identical to *return 666;* (if the parser could handle the latter).
- Since DECORATE's return statement can only return the results of
function calls (I do not want to spend the time necessary to make it
return arbitrary expressions), here are three functions to get around
this limitation:
* A_State - Returns the state passed to it. You can simulate A_Jump
functions with this.
* A_Int - Returns the int passed to it.
* A_Bool - Returns the bool passed to it.
- e.g. If you want to return the number 3, you use this:
return A_Int(3);
If you want to jump to a different state, you use this:
return A_State("SomeState");
- The A_Jump family of action functions now return the state to jump
to (NULL if no jump is to be taken) instead of jumping directly.
It is the caller's responsibility to handle the jump. This will
make it possible to use their results in if statements and
do something other than jump.
- DECORATE return statements can now return the result of a function
(but not any random expression--it must be a function call). To
make a jump happen from inside a multi-action block, you must
return the value of an A_Jump function. e.g.:
{ return A_Jump(128, "SomeState"); }
- The VMFunction class now contains its prototype instead of storing
it at a higher level in PFunction. This is so that
FState::CallAction can easily tell if a function returns a state.
- Removed the FxTailable class because with explicit return
statements, it's not useful anymore.
