tModLoader [Solved] Change texture from different file on override AI() code

[AyraHikari]

Hello, how to change texture file at AI() code?

For example, when NPC walk the texture is NPC_walk.png

public override string Texture => "NPCs/NPC_walk";

But when NPC is become something for example offensive mode in AI() code,
They should change texture to NPC_attack.png.

But since Texture code is read only, i can't change that.

I tried with this code, but it not override the current texture

texture = mod.GetTexture("NPCs/NPC_attack");
spriteBatch.Draw(texture, npc.Center, null, Color.White, 0f, new Vector2(16f, 16f), 1f, SpriteEffects.None, 0f);

The AI() code should be like this, and i expect work, but it got error Texture is read only

public override bool AI() {
    if (npc.ai[0] == 0) {
        Texture = "NPCs/NPC_walk";
        Main.npcFrameCount[npc.type] = 9;
    }
    else if (npc.ai[0] == 1) {
        Texture = "NPCs/NPC_attack";
        Main.npcFrameCount[npc.type] = 6;
    }
    else if (npc.ai[0] == 2) {
        Texture = "NPCs/NPC_magic";
        Main.npcFrameCount[npc.type] = 7;
    }
    else if (npc.ai[0] == 3) {
        Texture = "NPCs/NPC_defense";
        Main.npcFrameCount[npc.type] = 4;
    }

    return true;
}

My code is this, and works very well!

Main.npcTexture[npc.type] = mod.GetTexture("NPCs/NPC_atk"); // Texture
Main.npcFrameCount[npc.type] = 6; // Total frame count
