Resources

Debug monitor

Resource to easily be able to view server and client debug messages. (remotely)

Created as an example to demonstrate the use of on(Client)DebugMessage.

Camo vehicles

When this resource is enabled, boats will get the same color as the water, and planes will get the same color as the sky. What's not to like?

Created as an example to demonstrate the use of getWaterColor, getSkyGradient and RGB vehicle colors.

Function suggestions

Some functions I should work on sometime soon. (sort of my "TODO")

Server-side

-- None at the moment

Client-side

-- None at the moment

Both

setVehicleNitrousActivated ( vehicle theVehicle, bool toggle ) -- Being able to influence NOS would be great (should block GTA from disabling it as well)
isVehicleNitrousActivated ( vehicle theVehicle ) -- Obvious function is obvious
setVehicleNitrousRechargeDelay ( vehicle theVehicle, int delay ) -- Function to set the amount of time the driver has to wait to reactivate NOS
getVehicleNitrousRechargeDelay ( vehicle theVehicle )

setStreetLightsEnabled ( bool toggle ) -- Got to try and find the address for this first though
setBackgroundGunshotsEnabled ( bool toggle ) -- Gotta find this one as well.. again...
setBirdsEnabled ( bool toggle ) -- I hate those pesky poopers at times.. Besides, it doesn't fit in some circumstances.. Gotta find the address D:
areStreetLightsEnabled
areBackgroundGunshotsEnabled
areBirdsEnabled

setRainLevel ( float level ) -- Internally defined and "working", but not used. Needs slight fixing
getRainLevel ( ) -- Make an educated guess
resetRainLevel ( )

setPedBreath ( ped thePed, float breath ) -- For breath, as used underwater
getPedBreath ( ped thePed )

isEventAdded ( string eventName ) -- Should be fairly obvious
isEventHandlerAdded ( string eventName, element attachedTo[, function handlerFunction ] ) -- Should be fairly obvious as well

Event suggestions

Events which might be quite useful. I should work on these sometime soon.

Server-side

onElementCreated ( ) -- Said it will be very slow, but still, it's a quite useful event. Besides, if onElementDestroyed isn't slow, why would this be slow?
onVehicleNitrousActivated ( ) -- Should be fairly obvious
onVehicleNitrousDeactivated ( ) -- Should be fairly obvious
onVehicleTireStateChanged ( int tire, int state ) -- If you'd want vehicles with bulletproof wheels or something, you'd need to detect the state change first

Client-side

onClientElementCreated ( ) -- See server-side
onClientVehicleNitrousActivated ( ) -- See server-side
onClientVehicleNitrousDeactivated ( ) -- See server-side
onClientVehicleTireStateChanged ( int tire, int state ) -- See server-side
onClientVehicleDamage ( float loss ) -- Server-side version already exists, if only there'd be an easy way for it client-side...

FX functions

Doomed_Space_Marine did research on some particle effects on custom models. It would be very cool if we could make functions to do this instead, like we already can with some particle effects. (for instance: fxAddBlood) This would especially be very cool if we would be able to alter the fx, so for instance we could create colored smoke.

fxAddHeliKillBlood
fxAddCarWashEffect
fxAddCement
fxAddClouds -- Note: It's a rather vague type of effect
fxAddCokeTrail
fxAddShower -- Note: Classed as "some water effect", but unknown what type of water effect. Assuming shower
fxAddSmoke
fxAddPour -- Seems more like it should be fxAddPee or fxAddPiss though
fxAddLeaves
fxAddSpray
fxAddFireExtinghuiserEffect
fxAddFlamethrowerFlame
fxAddInsects

Weather functions

Warning: This section is for serious weathermen only!

I recently noticed how many functions MTA actually has to influence the weather. It would be quite awesome if we would be able to influence litterally every factor.

-- We currently have
setWaveHeight
setSkyGradient
setWindVelocity
setCloudsEnabled
setWaterColor

-- We'll need
setRainLevel
setHeatWaveIntensity
setFogDensity
setLightningEnabled -- (I really hope there is some way to separate lightning from rainy weathers)
-- Anything else?

P.S. x86: fix setWeatherBlended, nao

Memory addresses

Here are a couple of memory addresses which might be useful for implementing new functions, so I can't forget them.

Variables

Variables I've discovered through playing around with Cheat Engine

Purpose	Address	Address type	Comments
Rain	0x0C81324	float	Maximum used in SA: 1; Decreases over time; Doesn't create thunder; Already in the MTA source; Creates heavy static at high values
Fog distance	0x0B7C4F0	float	Sets a shitload of other variables as well; Lags at a very high values
-	-	-	-
LS Street lights enabler	0x0960CF4	bool (byte)	Automatically 1 at night (in LS); Setting this to 0 causes a new light corona to be created at all LS street lights

Functions

Functions which are setting the above variables. Got these from Cheat Engine as well.

Rain	0x072bc92 & 0x072c686	d9 1d 24 13 c8 00	fstp dword ptr [00c81324]	NOP-ing (one of) these functions causes LSODs when getting into vehicles
Fog distance	0x55fcc8, 0x5613a3 & 0x560a23	d9 5e 50	fstp dword ptr [esi+50]	NOP-ing (one of) these functions causes LSODs when close to an obstacle on foot
