Convert char to uint32_t

Question

Hello, I am trying to do the following:

 

for (int i = 0; i < 30; ++i)
                {

                    if (dwEff== i)
                    {
                        char szEff[256];
                        sprintf(szEff, "EFFECT_REFINED+EFFECT_SWORD_EFF%d", i);
                        m_swordRefineEffectRight = szEff;
                    }
                }

 

But when I compile I get the error that it couldn't convert char to uint32_t.

How could I make this possible? Thank you

Then you'll need a small formula like this, for keeping the same values of enum:

So, in that way, you'll get the effect value multiplied by 4 depending on effectID.

Output:

dwEff = 1
m_swordRefineEffectRight = EFFECT_REFINED + 114

dwEff = 5
m_swordRefineEffectRight = EFFECT_REFINED + 130

dwEff = 12
m_swordRefineEffectRight = EFFECT_REFINED + 158

It's impossible what you're trying to do, this could be done in python very easily, like:

m_swordRefineEffectRight = eval("EFFECT_REFINED + EFFECT_SWORD_EFF_%d" % i);

But in C++ there's no built-in method, just a work-around, and shitty ways.

 

I don't know how it's working your system but in your case, you need something very simple, not to evaluate an expression when you can use effectSwordStartID + effectID:

m_swordRefineEffectRight = EFFECT_REFINED + EFFECT_SWORD_EFF_START + dwEff;

You just need to have the values ordered ascendingly.

We should probably see the rest of the code, but the compiler is telling you that with a reason. You cannot convert an array of chars to a numerical type. A solution would be setting m_swordRefineEffectRight = dwEff but then again, I am not really sure what you are trying to accomplish here.

Thanks for answering.

What I am trying to do is replace this:

 

                 if (dwEff == 1)
                    m_swordRefineEffectRight = EFFECT_REFINED+EFFECT_SWORD_EFF1;
                else if (dwEff == 2)
                    m_swordRefineEffectRight = EFFECT_REFINED+EFFECT_SWORD_EFF2;
                else if (dwEff == 3)
                    m_swordRefineEffectRight = EFFECT_REFINED+EFFECT_SWORD_EFF3;
                else if (dwEff == 4)
                    m_swordRefineEffectRight = EFFECT_REFINED+EFFECT_SWORD_EFF4;
                else if (dwEff == 5)
                    m_swordRefineEffectRight = EFFECT_REFINED+EFFECT_SWORD_EFF5;
                else if (dwEff == 6)
                    m_swordRefineEffectRight = EFFECT_REFINED+EFFECT_SWORD_EFF6;

                **About 30 or 40 more**

 

for this:

 

for (int i = 0; i < 30; ++i)
                {

                    if (dwEff == i)
                    {
                        char szEff[256];
                        sprintf(szEff, "EFFECT_REFINED+EFFECT_SWORD_EFF%d", i);
                        m_swordRefineEffectRight = szEff;
                    }
                }

dwEff is an int value that identifies the value of the effect to give a weapon.

 

I guess I'll have to leave the long code as is, I thought it might be possible to reduce it to a for.

Thank you

Then you could do it as I said, it's the best method instead of using an array or something.

Can you show me the EFFECT_SWORD_EFF1....EFFECT_SWORD_EFF40 values from enum?

Entonces podrías hacerlo como dije, es el mejor método en lugar de usar una matriz o algo así.

¿Puede mostrarme los valores EFFECT_SWORD_EFF1 .... EFFECT_SWORD_EFF40 de la enumeración?

I currently have them like this:

 

        EFFECT_SMALLSWORD_EFF1, //dagger, fan, bell
        EFFECT_SMALLSWORD_EFF1_LEFT, //dagger, fan, bell
        EFFECT_BOW_EFF1, //bow
        EFFECT_SWORD_EFF1, // sword, two hand
        
        EFFECT_SMALLSWORD_EFF2, //dagger, fan, bell
        EFFECT_SMALLSWORD_EFF2_LEFT, //dagger, fan, bell
        EFFECT_BOW_EFF2, //bow
        EFFECT_SWORD_EFF2, // sword, two hand
        
        EFFECT_SMALLSWORD_EFF3, //dagger, fan, bell
        EFFECT_SMALLSWORD_EFF3_LEFT, //dagger, fan, bell
        EFFECT_BOW_EFF3, //bow
        EFFECT_SWORD_EFF3, // sword, two hand
        
        EFFECT_SMALLSWORD_EFF4, //dagger, fan, bell
        EFFECT_SMALLSWORD_EFF4_LEFT, //dagger, fan, bell
        EFFECT_BOW_EFF4, //bow
        EFFECT_SWORD_EFF4, // sword, two hand

Solved, thanks to VegaS for their help.

 

If anyone ever wants to do something similar, they could use something like this:

 

for (int i = 0; i < 30; ++i) 
                {
                    if (dwEff == i) 
                        m_swordRefineEffectRight = EFFECT_REFINED + 110 + (dwEff * 4); 
                }

 

The code is adequate to what I have, so you should change the number 110 and * 4 depending on what you want to do
                

Many thanks to the two people who responded, special thanks to Vegas.
