UScriptIt

Example of macro usage we need our auto-caster to go in first before the macros are parsed, some might require afterwards so we end up doing a 2 stage compile.

Shortening Locals

`define l local 
`define lb `{l} bool 
`define lf `{l} float
`define ls `{l} string 
 
`define elif else if

Iterators

`define i index
`define j ondex
`define li `{l} int `{i}
`define lj `{l} int `{j}

Automatic casts

Set/Check/Return

Macro

`define CheckRet(Obj) if(`Obj == none) return
`define SetToDefault(Obj, Var) `{Obj}.`{Var} = `{Obj}.Default.`{Var}
`define SetVar(Obj, Var) `{Obj}.`{Var} = `{Var}

Usage

`SetVar(`P, CustomGravityScaling);
`P.MaxDoubleJumpHeight = 110;	//87.0
`P.DoubleJumpThreshold = 200.0;	//160.0
`P.FallSpeedThreshold = 150.0;	//125.0
 
/** */
`CheckRet(`MProj()_`{P}(`{P}));
 
`SetVar(`MProj()_`{P}(`{P}), bCanDodge);
`SetVar(`MProj()_`{P}(`{P}), bCanWalldodge);

Output

Pawn.CustomGravityScaling = CustomGravityScaling;
Pawn.MaxDoubleJumpHeight = 110;	//87.0
Pawn.DoubleJumpThreshold = 200.0;	//160.0
Pawn.FallSpeedThreshold = 150.0;	//125.0
 
/** */
if(Plugin_Pawn(Pawn)== none) return;
 
Plugin_Pawn(Pawn).bCanDodge = bCanDodge;
Plugin_Pawn(Pawn).bCanWalldodge = bCanWalldodge;

Iterators

Macro

`define fore(this, tmpv) foreach `{this}(`{tmpv})
`define ifind(Ar) `{i} = `Ar.find('`n', `ac)
