3.2、uploadOrUpdateProp

3.2.1、Features

Upload or update game props

3.2.2、Input parameters

type Descriptions Required
requestId string Unique traceId, cannot be repeated Yes
gameProps array The list of all game items to be exported has no limit on the number of items that can be imported. Please refer to the following text for the format of the data. yes

3.2.3、gameProp

type Descriptions Required
id string The identification code for game items must be unique for each item to be identified. This ID will be used for all imports and exports. yes
cost double The number of tokens that this item may be worth. If it is a scope item, then each item is worth a token quantity. Appliances should be priced fairly in order to be accepted by our ecosystem. yes
type int 1:Items that can be chained、2: arean items yes
image string The graphics of the project to be exported. Game developers should host their own images to achieve renewability. Our recommended monitor size is 300 x 300. yes
name string The name should be unique and clearly specified. If two names are found, the latter one takes effect. An example is hierarchical, where the higher the level, the more difficult it is to achieve, and the corresponding increase in export value should be made. yes
