Spring RTS Engine

Is there a simple way to clear the build queue of a factory?
I have tried unit.stop() with no success. doesn't seem to work either.
2 indicates CMD_REMOVE, 64 stands for CONTROL_KEY.

Any suggestions?

Also storing command ids as float doesn't seem to make much sense to me. Is there any alternative way of issuing custom commands?

commands work same as for humans, so instead of ctrl-modifier try right mouse-button-modifier to reduce queue.
Then spam right-clicks on all buildoptions. (bit stupid, but iirc that worked)

Thanks for the quick response. Although replacing 64 with 16(RMB) doesn't alter the queue :/

Edit: After using 255 (all possible modifier keys mashed at once) it worked :D

for CMD_REMOVE you have to use options.alt in order for it to interpret params as command ids.

From what i see alt and control should be sufficient, e.g. 192 (tested)
