Love Graphics

When to use this skill

{{SKILL_DESCRIPTION}} Use this skill when working with drawing operations, sprites, animations, shaders, or any visual rendering in LÖVE games.

Common use cases

• Drawing shapes, images, and text
• Creating animations and particle effects
• Implementing custom shaders and post-processing effects
• Managing sprites and sprite batches
• Handling screen transitions and visual effects

Examples

Drawing a colored rectangle

-- Draw a red rectangle
function love.draw()
  love.graphics.setColor(1, 0, 0, 1)  -- RGBA: red, fully opaque
  love.graphics.rectangle("fill", 100, 100, 200, 150)
end

Loading and drawing an image

local image

function love.load()
  image = love.graphics.newImage("sprite.png")
end

function love.draw()
  love.graphics.draw(image, 200, 200, 0, 2, 2)  -- Draw at 200,200 with 2x scale
end

Best practices

• Load graphics resources in love.load() to avoid delays during gameplay
• Use sprite batches for efficient drawing of many identical sprites
• Consider using canvas objects for complex compositions
• Be mindful of coordinate system (0,0 is top-left by default)
• Use appropriate image formats: PNG for transparency, JPEG for photos

Performance considerations

• Too many draw calls can cause performance issues
• Large images consume more memory
• Complex shaders impact GPU performance
• Frequent state changes (color, blend mode) can be expensive
• Particle systems can be CPU-intensive with many particles

Platform compatibility

• Desktop (Windows, macOS, Linux): Full graphics support including shaders
• Mobile (iOS, Android): Full support but some shader features may be limited
• Web: Good support but some advanced features may not be available
