(adsbygoogle = window.adsbygoogle || []).push({}); Hello NGU

I have been messing around with Engine text and shader functions and i thought i would just remake it and after doing it there really simple to understand, but anyways i thought i would release this as it kinda pointless but im sure alot people will find it neat and useful Happy

You will need to use these function in a function that runs every frame, i normally hook to CG_DrawNightVisionOverlay and you can find that here 0x42FC8 (as the function is pointless)

This should let u be able to do the type writter effects

    

#define cgArray 0xE22F18



int CG_GetLocalClientGlobals(int mod)

{

	return *(int*)cgArray + mod; // cg_t

}



int CG_GetLocalClientTime()

{

	return *(int*)(CG_GetLocalClientGlobals(0x4838C));

}

    

struct GfxCmdHeader

{

	unsigned short byteCount;

	char id;

	char ui3d;

};



union GfxColor

{

	unsigned int packed;

	char array[4];

};



struct GfxCmdDrawText2D

{

	GfxCmdHeader header;

	int type;

	float x;

	float y;

	float w;

	float h;

	float rotation;

	void *font;

	float xScale;

	float yScale;

	GfxColor color;

	int maxChars;

	int renderFlags;

	int cursorPos;

	char cursorLetter;

	GfxColor glowForceColor;

	int fxBirthTime;

	int fxLetterTime;

	int fxDecayStartTime;

	int fxDecayDuration;

	int fxRedactDecayStartTime;

	int fxRedactDecayDuration;

	void *fxMaterial;

	void *fxMaterialGlow;

	float padding;

	char text[3];

};



struct GfxCmdStretchPic

{

	GfxCmdHeader header;

	void *material;

	float x;

	float y;

	float w0;

	float w;

	float h;

	float s0;

	float t0;

	float s1;

	float t1;

	GfxColor color;

};



0x794980 - void R_ConvertColorToBytes(const float *colorFloat, char *colorBytes);

0x769F6C - GfxCmdHeader * R_GetCommandBuffer(int renderCmd, int bytes);

0x76A9B8 - bool SetDrawText2DGlowParms(GfxCmdDrawText2D *cmd, const float *color, const float *glowColor);

0x763220 - void * Material_RegisterHandle(const char *name, int imageTrack, bool errorIfMissing, int waitTime)

0x75A2C0 - void * R_RegisterFont(const char * name, int imageTrack);

0x3DA948 - bool Dvar_GetBool(dvar_t * dvar);

0x3DA628 - dvar_t * Dvar_FindMalleableVar(const char *dvarName);



bool DvarGetBool(const char *dvarName)

{

	if (Dvar_GetBool(Dvar_FindMalleableVar(dvarName)))

		return true;

	else

		return false;

}



void R_AddCmdDrawTextInternal(const char *text, const char *fontName, float x, float y, float scale, const float *color)

{

	if (*text)

	{

		int len = strlen(text);

		GfxCmdDrawText2D * cmd = (GfxCmdDrawText2D *)R_GetCommandBuffer(0x10, (len + 0x6 & 0xFFFFFFFC);

		if (cmd)

		{

			cmd->type = 0;

			memcpy(cmd->text, (char *)text, len);

	}

}

}

You will also need the dvar_t struct in order to use the DvarGetBool function i made, You can find them here You must login or register to view this content.

opd_s R_RegisterFont_s = { 0x75A2C0, TOC };
void*(*R_RegisterFont)(const char * font, int imageTrac) = (void*(*)(const char *, int))&R_RegisterFont_s;
opd_s Material_RegisterHandle_s = { 0x763220, TOC };
void*(*Material_RegisterHandle)(const char *name, int imageTrack, bool errorIfMissing, int waitTime) = (void*(*)(const char *, int, bool, int))&Material_RegisterHandle_s;
opd_s R_ConvertColorToBytes_s = { 0x794980, TOC };
void(*R_ConvertColorToBytes)(const float *colorFloat, char *colorBytes) = (void(*)(const float *, char*))&R_ConvertColorToBytes_s;
opd_s R_GetCommandBuffer_s = { 0x769F6C, TOC };
GfxCmdHeader*(*R_GetCommandBuffer)(int renderCmd, int bytes) = (GfxCmdHeader*(*)(int,int))&R_GetCommandBuffer_s;

do a memory dump of the game and search fonts/ and ull find bunch of font names

u need to call engine text on a hook
