Add some polish to your game¶
Congratualations! You have reached the last part of the tutorial series!
Stop Falling Forever¶
Currently if you fall off the platform you will fall forever. To stop the
character falling infinitely we can put a platform below which will kill the
character when fall onto it. Gamma provides the gma.deathPlatform for
this purpose. Let’s create one under the main platforms and paint it red:
// Create a deathplatform type
types : {
lava : ['deathPlatform', {template : 'redcube', depth:50}]
}
// Add this lava / death platform to the list of entities
entities : [
{type:'lava', top:-10, left:-50, width:1000, height:50},
]
Respawn the Character¶
We will also bind a key to respawn the character (for when it dies).
Register the method gma.manager.respawn to be called when the letter
‘r’ (for reload/restart/respawn) is pressed:
gma.keyHandler.register(82, function(e) {
manager.respawn("main");
});
The last Final result¶
Now that you’ve finished, the game description (game.js) should look very
similar to this:
require([
'gma/base',
'gma/manager',
'gma/entities/character',
'gma/events',
'gma/entities/enemy',
'gma/entities/door'
],
function(gma) {
var manager = gma.manager({
width : 600,
height : 500
});
manager.character = gma.character({
left : 0,
bottom : 0,
width : 3,
height : 6,
depth : 3,
template : 'gorilla'
});
manager.addCustomDefinitions({
templates : {
greencube : ['meshTemplate', {
mesh : gma.unitCubeInfo.mesh,
material : {color : "#090"}
}],
gorilla : ['colladaTemplate',
{
collada : {
document : 'gorilla.dae'
},
yRot : 1.57,
yOffset : -0.5,
yScale:0.7
}],
brickscube : ['meshTemplate', {
mesh : gma.unitCubeInfo.mesh,
texture : {

},
