Question 1

How do I prevent blurry images when zooming with Gamera?

Accepted Answer

Set LÖVE's default filter to 'nearest' using love.graphics.setDefaultFilter('nearest', 'nearest') or apply it per image, as linear filtering causes blur during transformations.

Question 2

Why do I see seams around my tiles with Gamera?

Accepted Answer

Seams occur due to OpenGL texture filtering and floating-point precision. Fix it by using quads with 2-pixel borders filled with edge colors, and consider using the anim8 library for easier quad management.

Question 3

How can I disable clamping in Gamera?

Accepted Answer

You can't directly disable it, but mimic it by expanding world boundaries with setWorld to create a border, as explained in the FAQ—for example, using negative values for left and top.

Question 4

Gamera vs LÖVE's built-in camera functions: which is better?

Accepted Answer

Gamera provides more robust features like boundary management and optimized drawing, while LÖVE's basics might suffice for simple cameras. Choose Gamera for complex scrolling, zooming, or rotation needs.

Question 5

How to optimize drawing with Gamera's visible area?

Accepted Answer

Use the l,t,w,h parameters passed to the draw callback to cull off-screen objects—for instance, only draw tiles or entities within this rectangle to boost performance.

Question 6

Does Gamera support smooth camera movement or easing?

Accepted Answer

No, it doesn't include built-in easing functions. You'll need to implement smooth movement manually in LÖVE's update loop, interpolating positions before calling setPosition.

Question 7

Can I use multiple cameras with Gamera in one game?

Accepted Answer

Yes, create multiple gamera instances for views like split-screen or minimaps by managing each camera's window and world separately with setWindow and setWorld.
