dbde0971ef - removed the second 'calculated' return value from the damage function call in GetMissileDamage as it is no longer needed or even code being generated for. 2016-11-06 10:28:01 +01:00

d433fb76c9 - completed the list of AActor exported member variables, with the exception of a few things that cannot be done yet.
Note that AActor::Inventory needed to be renamed because defining this symbol within AActor would hide the global type of the same name!

9563045305 - moved declaration of native fields into the respective class definitions.
This bypasses a declaration in the script in favor of a simpler implementation. In order to work it is always necessary to have an offset table to map the variables to, but doing it fully on the native side only requires adding the type to the declaration.

a45523fb63 - scriptified A_SpawnFly.
- added support for global variables to the code generator - not the compiler, though. For the handful of entries this is needed for it may just as well be done manually. So far FLevelLocals level is the only one being exported.
- fixed: The VM disassembler truncated 64 bit pointers to 15 digits because the output buffer was too small.
- resolve entire FxSequences instead of aborting on the first failed entry. This allows to output all errors at once.

88fd47247d - scriptified several trivial functions from a_action.cpp. 2016-11-01 16:32:47 +01:00

e620c9bd7d - scriptified parts of a_bossbrain.cpp. Some things cannot be done yet, the script code is there but commented out.
- exported thinker iterator and drop item chain to scripting. Unlike its native counterpart the script-side iterator is wrapped into a DObject to allow proper handling for memory management.
- fixed: The VMFunctionBuilder only distinguished between member and action functions but failed on static ones.
- fixed: FxAssign did not add all needed type casts. Except for purely numeric types it will now wrap the expression in an FxTypeCast. Numeric handling remains unchanged for both performance reasons and not altering semantics for DECORATE.
- exported all internal flags as variables to scripting. They still cannot be used in an actor definition.
- make ATAG_STATE the same as ATAG_GENERIC. Since state pointers exist as actual variables they can take both values which on occasion can trigger some asserts.
- gave PClass a bExported flag, so that scripts cannot see purely internal classes. Especially the types like PInt can cause problems.

Todo: we need readonly references to safely expose the actor defaults. Right now some badly behaving code could overwrite them.

f8ccda2dc8 - scriptified A_Mushroom to test something a bit more complex.
- fixed: FxMinusSign trashed local variables that were used with negation.
- fixed: FxConditional only handled ints and floats, but not pointers and strings.
- fixed: A 'no states in non-actors' error was triggered, even for classes without any states.

c7347608a4 - scriptified A_FatAttack*.
- swapped parameters of two-parameter VelToAngle method, so that internal and script version are in line.
- fixed parameter asserts to handle NULL pointers properly.

823c52aeb2 - scriptified the functions in a_possessed.cpp and added the needed exports and constants.
- fixed: Script functions did not receive the function name when being created.
- relaxed the asserts for PARAM_STATE, because the VM knows nothing about ATAG_STATE. Any state variable's content (e.g. Actor.SeeState) will receive ATAG_GENERIC, rather than ATAG_STATE.
- added a 'NeedResult' flag so that certain operations can create shorter code if the result of the expression is not needed. So far only used for postdecrement/increment statements on local variables (which is the most frequent case where this matters.)
- fixed postincrement and decrement for local variables. Due to the result preservation semantics it created faulty code.

9f8a5dae21 - scriptified A_BruisAttack.
- removed 'self' as a dedicated token. Internally this gets handled as a normal but implicitly named variable so the token just gets in the way of proper processing.
- removed P_ prefix from SpawnMissile export.
- fixed a crash with misnamed function exports.

a2116fc7bf - created an export for P_SpawnMissile so that I can do some tests with functions.
- allow class extensions.

These are separate blocks in different files that get concatenated to one class body for processing. The reason is to allow spreading the many functions in Actor over multiple files, so that they remain manageable. For example, all the Doom action functions should be in their respective files, but their symbols need to be in Actor. To extend a class, both files need to be in the same translation unit, so it won't allow user-side extension of internal classes.

ae14993ba4 Fixed: Possible invalid processing for Crash states that immediately destroy the actor
- Setting an actor's Crash state has the potential to destroy the actor if
  the Crash state has one or more 0-tic states that end with Stop. This
  was not taken into account when the object's Z velocity was 0, but it
  was under the floor anyway.

b1a83bfd26 - started with cleanup and separation of DECORATE code.
* everything related to scripting is now placed in a subdirectory 'scripting', which itself is separated into DECORATE, ZSCRIPT, the VM and code generation.
 * a few items have been moved to different headers so that the DECORATE parser definitions can mostly be kept local. The only exception at the moment is the flags interface on which 3 source files depend.

5dc94a10c3 Added A_SetInventory.
- Sets the absolute amount of an inventory actor.
- Limits itself to the range [0, MaxAmount]. Setting beyondMax to true disregards the MaxAmount. Default is false.

c56d2eecb0 - rewrote AActor::DestroyAllInventory so that it clears the item's link to its owner and the owner's inventory list before destroying them.
There have been reports about crashes in here with Linux that point to some of the code that gets called here doing unwanted things on the owner, so with these links cleared that should no longer be possible.

74b8e9f286 - Don't use Normalized180() on angles. This could result in ranges being wrongly inverted.
- Fixed properties not having the proper indices.
- Use ViewPos-to-actor instead of measuring actor-to-actor.
- Use the actual camera instead of the actor so camera textures can work.

f1ba19073f - split Damage into two variables: DamageVal for the old constant and DamageFunc for the DECORATE function.
The way this was done was a major headache inducer, requiring reconstruction of the function each time the value was changed and in general made actor damage a major hassle.
There was a DECORATE wrapper to mimic the original behavior but this looked quite broken because it completely ignored the different semantics of both damage calculation types.
It also made it impossible to determine if damage was a function or a value.
This accessor has been reverted to what it should be, only returning the constant, which now is -1 for a damage function. I am sorry if this may break the odd mod out but a quick look over some DECORATE-heavy stuff showed that this was never combined in any of them so that accessing 'damage' in DECORATE code depended on an actual damage function.

To get proper damage, a future commit will add a DECORATE function which calls AActor::GetMissileDamage.

c4357bd352 Tracer pointer is no longer a safe candidate for storing player morph pointers. Instead, actors must have a new, non-manipulatable pointer. This fixes the following circumstances:
- Crashes occurred if a particular actor was a tracer to the player and the actor was not gone by the time the player unmorphs.
- Failed unmorphs occur if tracer was manipulated through means like A_RearrangePointers, etc.

4993018520 - fixed: Actor velocity requires an upper limit to prevent uncontrolled accumulation, as can happen when multiple exploding and pushable objects overlap. The value 5000 was chosen because it is high enough to not occur under regular circumstances and small enough to prevent severe slowdowns. In the old fixed point code the lack of such a check just caused random overflows. 2016-08-31 09:18:59 +02:00

1d434add50 - fixed: monsters which were made friendly by the MBF map flag lost their friendliness when being revived with Thing_Raise. 2016-08-04 17:14:31 +02:00

dfed6ac1fb Added SpriteAngle and SpriteRotation properties.
- Includes four functions, A_SetSprite(Angle/Rotation) and GetSprite(Angle/Rotation).
- SpriteRotation offsets the angle of the sprite, allowing for actors to move backwards or sideways for example.
- SpriteAngle requires +SPRITEANGLE and sets the actor's sprite to the absolute rotation found at that angle. Overrides SpriteRotation once the flag is on.

cfaa3e3fa9 - changed action function interface so that callers can be identified directly, instead of guessing it from looking at the parameters.
With arbitrary PSP layers the old method was no longer safe because the layer ID was not available in the action function.

1703842a94 - fixed some issues with teleport fog:
* many calls didn't use TELEFOGHEIGHT, mostly those coming from external code submissions that never were tested on anything but Doom. Addressed by adding this value inside P_SpawnTeleportFog and making the distinction between projectiles and non-projectiles from P_Teleport also part of this function.
* there were still a few places which spawned the teleport fog directly, skipping all the added features of P_SpawnTeleportFog.

3aee8a3eee - Fixed a mistake in GiveInventory refactoring.
'give item' stopped working because commit 7b35f32f3d and 6aca7604eb didn't take account that give cheat with zero amount should not touch the item amount.
