How to get a texture to a UTexture variable?

Hello and good afternoon everybody,

I have been messing with unreal for a while already, and I am trying to make a simple HUD for my game, which will use textures, I am using a class of my own which is inherits from AHUD, no changes in constructors or destructors, just custom methods to draw the heads up display, however, I am still struggling on on how I can get a texture and draw it to the screen using the method “DrawTextureSimple”, I succeeded in doing so by setting the texture in blueprints through a blueprintable method I created in C++ (method setTexture), however I cannot yet understand how to do the same in pure C++ (trying through the method setTextureC)…

Can anyone explain to me how to do it?

*I am a noob…TT__TT

Thanks for the attention,

*CODE:

-FILE “DTHUD.h”:

#pragma once

#include "GameFramework/HUD.h"
#include "DTPlayerState.h"

#include "DTHUD.generated.h"

UCLASS()
class ACTIONSYSTEM_API ADTHUD : public AHUD
{
	GENERATED_BODY()
public:	

	UTexture* texture;

	UFUNCTION(BlueprintCallable, Category = "DT HUD")
	ADTPlayerState* GetPlayerState();

	UFUNCTION(BlueprintCallable, Category = "DT HUD")
	void SetPlayerState(ADTPlayerState* newPlayerState);

	UFUNCTION(BlueprintCallable, Category = "DT HUD")
	UTexture* GetTexture();

	UFUNCTION(BlueprintCallable, Category = "DT HUD")
	void SetTexture(UTexture* newTexture);

	UFUNCTION(BlueprintCallable, Category = "DT HUD")
	void SetTextureC();

	void DrawHUD();

protected:
	ADTPlayerState* dTPlayerState;

};

-FILE “DTHUD.cpp”:

#include "ActionSystem.h"
#include "DTHUD.h"

void ADTHUD::DrawHUD(){
	if (dTPlayerState){
		DrawTextureSimple(texture, 0, 0, 1, false);
	}
}

void ADTHUD::SetPlayerState(ADTPlayerState* newPlayerState){
	dTPlayerState = newPlayerState;
}

ADTPlayerState* ADTHUD::GetPlayerState(){
	return dTPlayerState;
}

void ADTHUD::SetTexture(UTexture* newTexture){
	texture = newTexture;
}

UTexture* ADTHUD::GetTexture(){
	return texture;
}

void ADTHUD::SetTextureC(){

	static ConstructorHelpers::FObjectFinder<UTexture2D> MyObj(TEXT("/Game/ThirdPerson/test"));
	texture = MyObj.Object;
}

Hello,

You can use AHUD::DrawTexture function:

UFUNCTION(BlueprintCallable, Category=HUD, Meta=(AdvancedDisplay="9"))
void DrawTexture
(
    UTexture * Texture,
    float ScreenX,
    float ScreenY,
    float ScreenW,
    float ScreenH,
    float TextureU,
    float TextureV,
    float TextureUWidth,
    float TextureVHeight,
    FLinearColor TintColor,
    EBlendMode BlendMode,
    float Scale,
    bool bScalePosition,
    float Rotation,
    FVector2D RotPivot
)

Please also note that the line

static ConstructorHelpers::FObjectFinder<UTexture2D> MyObj(TEXT("/Game/ThirdPerson/test"));

should be placed in HUD’s constructor.

Have a great day!
