action role playing game type spells..like fireballs ice spells,examples of magic and slash double slash example of melee attacksjust sprites, particle emitters, objects.... depends on what you are doing with your spells..
are they just effects? draw sprites or particles..
are actually colliding and having an effect? might be better to create some fancy "bullet" ..a magic bullet type object
really depends on how you have your game set up..
need more information ;o)
draw_sprite()might not be up to the task.
draw_sprite_ext()and draw multiple lightning sprites with their angles, lengths and positions all done with maths to connect them into something that looks like a lightning chain...Perhaps you'd set up some primitives and texture them...Perhaps you'd go the shader route and manipulate the individual pixels using shader maths to create the lightning effect. None of these are necessarily "better" than any others (some might be easier on the processor, though), but whatever you do, it's not necessarily going to change how you'd draw a fireball. You'd draw your fireball the same way as you did at the start, but change how you do things for the chain lightning.
