Problem it solves

A flying bat and a low fireball collide in 2D top-down coordinates, but the bat is flying high above the fireball and should not take damage.

What this block does

Checks if two sprites overlap in vertical height (the Z-axis). Works best inside regular sprite overlap events to make collisions 3D-aware.

The block

Block ID: rcRender_isSpritesOverlapZ

Parameters

Returns

boolean — true if the sprites overlap along the vertical Z dimension.

Example

sprites.onOverlap(SpriteKind.Enemy, SpriteKind.Projectile, function (enemy, proj) {
    if (Render.isSpritesOverlapZ(enemy, proj)) {
        proj.destroy()
        enemy.destroy()
    }
})
