| ROM address data | |
|---|---|
| Length | 0x16 |
| Type | Code |
| Name | createPlayerEntity |
| Description | Creates an entity for a player |
| Arguments/Return value | Y+A = [pointer32] Entity pointer Return A = [unit16] Entity ID |
| Return type | RTL |
This is the same as $80:825E, but with the following differences:
- Searches entity slots in forward order instead of reverse. This will guarantee that the two player entities are in the first two slots.
- This was possibly meant to guarantee player entities get assigned a direct page with a zero low byte for faster RAM access, but for some reason the second player entity has 0x280 for its direct page.
- Only searches for an empty entity in the first 0x10 slots (out of 0x18 total slots). This shouldn't matter since this is only used for up to two player entities.
