These are built on top of the gamekit component which manages all the sprites for you. It can render quite a few million sprites at 60fps so there is plenty of opportunity to go wild graphically.<\/p>\n<p>These examples are just graphical tests for my nephews – the graphics are all the ownership of the original artists. We will be releasing worked examples with public domain images for anyone to download and experiment with.<\/p>\n<p>Once you assign a sprite sheet to the Gamekit component you can start adding the custom actions. (I recommend using <a href=\"https:\/\/www.codeandweb.com\/texturepacker\">texturepacker<\/a> or a tool which makes an atlas in the LibGDX format)<\/p>\n<p>These two functions are where the fun starts;<\/p>\n<pre>\r\nsprite_id = gamekit_sprite_create(gamekit, sprite_index, sprite_name, x, y, scale, angle, alpha)\r\n<\/pre>\n<pre>\r\ngamekit_sprite_update(gamekit, sprite_id, sprite_index, sprite_name, x, y, scale, angle, alpha)\r\n<\/pre>\n<p>Now we can write a simple function which you can attach to the on_tick event of your GameKit component.<\/p>\n<pre>\r\n--variables\r\ng_smoke_x = {}\r\ng_smoke_y = {}\r\ng_smoke_a = {}\r\ng_smoke_s = {}\r\n\r\n--main smoke heartbeat\r\nregister(\"smoke_tick\",\"smoke tick\",\"\")\r\nfunction smoke_tick()\r\n for i=1,10 do\r\n g_smoke_y[i] = g_smoke_y[i] + 10 --gravity\r\n g_smoke_a[i] = g_smoke_a[i] + 1 --angle\r\n g_smoke_s[i] = g_smoke_s[i] + 0.01 --scale\r\n gamekit_sprite_update(gamekit, i, -1, 'shield', g_smoke_x[i], g_smoke_y[i], g_smoke_s[i], 0, 180)\r\n end\r\nend\r\n<\/pre>\n<p>We will have these games and many more up on the Umajin SDK community site in May!<\/p>\n<p>Cheers<br \/>\n David<\/p>\n","protected":false},"excerpt":{"rendered":"<p>.
