Scripting commands

Effect creation:

hndl = ppEffectCreate ["effect_type", priority]; hndls[] = ppEffectCreate [["effect_type0", priority0], ["effect_type1", priority1], ...];

Effect cancellation:

ppEffectDestroy hndl; ppEffectDestroy [hndl0, hndl1, ..., hndlN];

Parameter setup:

hndl ppEffectAdjust [par0, par1, ..., parN];

Parameter application:

hndl ppEffectCommit time; [hndl0, ..., hndlN] ppEffectCommit time;

Effect permission:

hndl ppEffectEnable OnOf; [hndl0, ..., hndlN] ppEffectEnable OnOf;

Introduced with Arma 3 version1.56

Check if enabled:

ppEffectEnabled hndl;

Example

_hndl = ppEffectCreate ["colorCorrections", 1501]; _hndl ppEffectEnable true; _hndl ppEffectAdjust [1.0, 1.0, 0.0, [1.0, 0.1, 1.0, 0.75], [0.0, 1.0, 1.0, 1.0], [0.199, 0.587, 0.114, 0.0]]; _hndl ppEffectCommit 0; sleep 10; ppEffectDestroy _hndl;

Table of priorities

Priority defines sequence in which post effects are applied. The higher priority, the later the effect will be applied, on top of the others.
