Implemented types are: "base", "spray", "rotate" and "burst".
Parameters:
| Name | Type | Description |
|---|---|---|
emitter |
JSON description of the emitter |
|
x |
X coordinate for the parser. |
|
y |
Y spawning coordinate for the parser. |
|
w |
Width for the parser. |
|
h |
Height for the parser. |
|
params |
Parameters for the emitter. |
|
parent |
Sprites container. |
|
bulletList |
Array in which the bullets will be pushed. |
- Source:
Returns:
An instance of the requested emitter if emitter.type could be parsed, null otherwise.

(static) parseEmitter(emitter, x, y, w, h, rate, power, parent, bulletList) → {*}
Returns a new emitter suitable for the player (i.e. not aiming at it) with given parameters. The emitters' JSON description has the following fields:
- type: string identifying the emitter class (@see BHell.BHell_Emitter_Factory#create),
- params: parameters for the emitter (see
BHell.BHell_Emitter_Baseand derived classes for its content).
Parameters:
| Name | Type | Description |
|---|---|---|
emitter |
JSON description for the emitter. |
|
x |
X coordinate for the parser. |
|
y |
Y spawning coordinate for the parser. |
|
w |
Width for the parser. |
|
h |
Height for the parser. |
|
rate |
Rate of fire rank for the emitter (D = 1, C = 2, B = 3, A = 4, S = 5), it multiplies the emitter's period. |
|
power |
Fire power rank for the emitter (D, C, B, A, S), enables some emitters instead of others. |
|
parent |
Sprites container. |
|
bulletList |
Array in which the bullets will be pushed. |
- Source:
Returns:
An instance of the requested emitter if emitter.params.ranks contains power, null otherwise.
