Pcx Scripting

PCX / Perception.cx scripting

Activation

Use when the task involves writing PCX scripts, game interaction via Perception.cx, Enma scripting, or AngelScript scripting.

Language selection

• Enma (primary): AOT/JIT compiled, C++-like syntax. Use for all new scripts. Full API below.
• AngelScript (deprecated): Being removed after Enma release. Only use for maintaining legacy scripts. Similar API surface, AngelScript syntax.

Enma conventions

• Colors/positions: always wrap — color(255, 255, 255, 255), vec2(10.0, 20.0).
• Float32 literals: 0.2f, not static_cast<float32>(0.2).
• Handles: create_*/load_* return encrypted int64. Pass back into draw/bind/destroy. Don't inspect.
• Casts: static_cast<T>(x) for numeric, reinterpret_cast<int64>(fn) for function pointers.
• Strings: std::string for values, const char* for read-only params. to_string(n) for numeric→string. "a" + "b" is illegal — use std::string("a") + "b".
• Arrays: std::vector<T> for dynamic, std::array<T, N> for fixed.

Lifecycle

int64 main() {
    // setup, register routines
    return 1;  // >0 = stay loaded, <=0 = unload immediately
}

Routines (per-frame callbacks)

int64 register_routine(int64 fn_handle, int64 data);
bool unregister_routine(int64 routine_handle);

// Callback shape:
void my_callback(int64 data) { /* data = second arg to register_routine */ }

// Usage:
int64 main() {
    register_routine(reinterpret_cast<int64>(my_callback), 0);
    return 1;
}

AngelScript API (deprecated)

Legacy API — use only for maintaining existing scripts. All new work in Enma.

Key differences from Enma

• Entry: int main() (return >0 = persistent, <=0 = unload)
• Callbacks: register_callback(fn, every_ms, data_index) — not routines
• GUI: subtab/panel model, not sidebar sections
• Arrays: array<T> instead of std::vector<T>
• Strings: native string type
• Proc: requires deref() for cleanup, has read_struct with dictionary descriptors
• Render: raw float params, not vec2/color types
• Has engine-specific API (Unreal, Fortnite, Rust helpers)

Lifecycle

int main() {
    register_callback(on_tick, 16, 0);  // every 16ms
    return 1;  // >0 = stay loaded
}
void on_unload() { /* cleanup */ }
void on_tick(int callback_id, int data_index) { /* per-frame */ }
// register_callback(fn, every_ms, data_index, render_on_top=false) → callback ID
// unregister_callback(id)

Logging

void log(const string& message);
void log_error(const string& message);
void log_console(const string& message);
void log_console_error(const string& message);
string get_username();

Proc API differences

proc_t ref_process(uint pid);
proc_t ref_process(const string& name);
void proc_t::deref();  // MUST call when done (also if alive() == false)

// Struct reads via dictionary descriptor:
dictionary desc = {{"health", "i32"}, {"pos_x", "f32"}, {"pos_y", "f32"}, {"pos_z", "f32"}};
dictionary result;
proc.read_struct(addr, result, desc);
int64 hp = cast<int64>(result["health"]);

// Module lookup (different signature):
uint64 base, size;
proc.get_module("game.dll", base, size);

// VAD snapshot returns array<dictionary@>:
array<dictionary@>@ vad = proc.get_vad_snapshot(true);

Render API differences

// Raw float params instead of vec2/color:
void draw_rect(float x, float y, float w, float h,
    uint8 r, uint8 g, uint8 b, uint8 a,
    float thickness, float rounding, uint8 rounding_flags);
void draw_text(const string& text, float x, float y,
    uint8 r, uint8 g, uint8 b, uint8 a,
    uint64 font, int effect,
    uint8 er, uint8 eg, uint8 eb, uint8 ea, float effect_amount);
// effect: TE_NONE=0, TE_OUTLINE=1, TE_SHADOW=2, TE_GLOW=3
// rounding: RR_TOP_LEFT, RR_TOP_RIGHT, RR_BOTTOM_LEFT, RR_BOTTOM_RIGHT
void get_view(float& w, float& h);
void get_text_size(uint64 font, const string& text, int maxw, int maxh, float& w, float& h);
