Fix for Stair Warp: A Game-Changing Solution for Pokémon FireRed

Pokémon FireRed, a classic game, has been a favorite among gamers for years. However, like any other game, it's not immune to bugs and glitches. One such issue is the stair warp problem, which can be frustrating for players. Fortunately, a fix has been discovered and implemented, and in this article, we'll delve into the details of this solution.

The stair warp issue occurs when the player sprite is moved using the x and y offsets (x2 and y2 fields of the Sprite struct) instead of the actual x and y positions. This can cause the player to clip through walls or floors, resulting in an unpleasant gaming experience. To understand this issue better, let's take a look at the code.

The stair warp issue is caused by the way the player sprite is moved during a stair warp. Instead of using the actual x and y positions, the game uses the x and y offsets (x2 and y2 fields of the Sprite struct). This can be seen in the following code snippet:

// Code snippet from the original Pokémon FireRed game
void Task_StairWarp(void) {
    // ...
    sprite->x += sprite->x2;
    sprite->y += sprite->y2;
    // ...
}

As you can see, the game is using the x and y offsets (x2 and y2 fields of the Sprite struct) to move the player sprite. This is the root cause of the stair warp issue.

To fix the stair warp issue, we need to modify the code to use the actual x and y positions instead of the x and y offsets. One way to do this is to check if Task_StairWarp is active and add the x2 and y2 fields of the linked sprite to the player's shadow position. This can be seen in the following code snippet:

// Code snippet from the fixed Pokémon FireRed game
void Task_StairWarp(void) {
    // ...
    if (is_task_active(Task_StairWarp)) {
        sprite->x += sprite->x2;
        sprite->y += sprite->y2;
        // Add x2 and y2 fields of the linked sprite to the player's shadow position
        sprite->shadow_x += sprite->x2;
        sprite->shadow_y += sprite->y2;
    }
    // ...
}

By adding the x2 and y2 fields of the linked sprite to the player's shadow position, we ensure that the player sprite is moved correctly during a stair warp.

The stair warp issue in Pokémon FireRed is a frustrating problem that can be fixed by modifying the code to use the actual x and y positions instead of the x and y offsets. By checking if Task_StairWarp is active and adding the x2 and y2 fields of the linked sprite to the player's shadow position, we can fix this issue and provide a better gaming experience for players.

A: The stair warp issue is a problem in Pokémon FireRed where the player sprite is moved using the x and y offsets (x2 and y2 fields of the Sprite struct) instead of the actual x and y positions. This can cause the player to clip through walls or floors, resulting in an unpleasant gaming experience.

Q: How do I know if I have the stair warp issue in my Pokémon FireRed game?

A: If you're experiencing the stair warp issue, you may notice that the player sprite is clipping through walls or floors when you're walking up or down stairs. You may also notice that the player sprite is not moving correctly when you're using the stairs.

Q: How do I fix the stair warp issue in my Pokémon FireRed game?

A: To fix the stair warp issue, you need to modify the code to use the actual x and y positions instead of the x and y offsets. One way to do this is to check if Task_StairWarp is active and add the x2 and y2 fields of the linked sprite to the player's shadow position.

Q: What is the code change required to fix the stair warp issue?

A: The code change required to fix the stair warp issue is to modify the Task_StairWarp function to use the actual x and y positions instead of the x and y offsets. You can do this by adding the following code:

// Code snippet from the fixed Pokémon FireRed game
void Task_StairWarp(void) {
    // ...
    if (is_task_active(Task_StairWarp)) {
        sprite->x += sprite->x2;
        sprite->y += sprite->y2;
        // Add x2 and y2 fields of the linked sprite to the player's shadow position
        sprite->shadow_x += sprite->x2;
        sprite->shadow_y += sprite->y2;
    }
    // ...
}
